Friction Loss
NPSH - Net Positive Suction Head
IMPORTANT!
NPSHA should exceed NPSHR for optimum pump performance and to prevent severe pump damage.
NPSH Example - Suction Lift
NPSHA = Ha - Hvp - Hf - Hs
Ha = Absolute Pressure
Hvp = Vapor Pressure
Hf = Friction Losses
Hs = Distance of liquid level above or below impeller
eye (if level is above eye, Hs is positive. If level is
below the eye, Hs will be negative.)

CAPACITIES - GALLONS PER MINUTE
Example 1:
Example 2:
Elevation = 500 ft above sea level
Water Temp = 70o F
Suction Head (Hs) = 13 feet
Capacity = 300 Gallons per Minute (GPM)
Suction Pipe Length (Steel) = 13 feet
Pipe Diameter = 4 inches
Elevation = 500 ft above sea level
Water Temp = 70o F
Suction Head (Hs) = 13 feet
Capacity = 500 Gallons per Minute (GPM)
Suction Pipe Length (Steel) = 13 feet
Pipe Diameter = 4 inches
Ha = 33.3 feet (From pg.12- Atmospheric Pressure)
Hvp = .84 feet head (From pg.12- Prop. of Water)
Hf = (9.19/100) * 13’ + (9.19/100) * 12’ = 1.19 (Pipe
Losses) + 1.10(Fitting Losses) = 2.29 feet
Hs = 13 feet
Ha = 33.3 feet (From pg.12- Atmospheric Pressure)
Hvp = .84 feet head (From pg.12- Prop. of Water)
Hf = (23.668/100) * 13’ + (23.668/100) * 12’ = 3.08 (Pipe
Losses) + 2.84 (Fitting Losses) = 5.92 feet
Hs = 13 feet
NPSHA = 33.3’ - .84’ - 2.29 - 13’ = 17.2 feet
NPSHR for DB3 @ 300GPM = 11 feet
17.2 > 11 Acceptable
NPSHA = 33.3’ - .84’ - 5.92 - 13’ = 13.54 feet
NPSHR for DB3 @ 300GPM = 17 feet
13.54 ≯ 17 NPSHR exceeds NPSHA, Cavitation occurs

Flow Measurement
Estimating Output from Pipe - Horizontal Open Discharge Method
For Full Flowing Pipes - The output in GPM can be approximated by constructing an L-shaped gauge like that
shown, with the short leg 4 inches long. Make the long leg to suit the pipe sizes and capacities for which the gauge
will be used (refer to table) and mark it in inches.
Lay the gauge along the top of the pipe with the short leg barely touching the stream of water, and note distance A.
Read the discharge rate from the table. Table is based on formula Q = 1.28 x A x D2.
Example: D = 3”; A = 15” : Q = 183 GPM

Partially Filled Pipe - Area Factor Method
Flow (Q) = A x H x F x 1.039
A = Area of pipe in square inches
H = Horizontal distance in inches
F = Effective area factor from chart
Pipe Area = Inside diameter2 x 0.7854
Example: Inside Diameter = 3.8”; H = 15”; F = .75”
A = 3.8 x 3.8 x 0.7854 = 11.34 sq. inches
F/D Ratio = .75/3.8 = 20%
F = 0.858
Q (GPM) = 11.34 x 15 x 1.039 = 177 GPM

Affinity Laws
Pump Speed / Impeller Diameter Change
Use the following laws of affinity to determine the effects of speed or impeller diameter changes when the desired
speed is not shown on pump curve:
H1
G1
Variables
R1
Existing Head in feet
Existing Gallons
per minute (GPM)
Existing Revolutions
per minute (RPM)
d1
P1
Existing diameter of
impeller in inches
Existing Brake
Horsepower (BHP)
H2
G2
R2
d2
P2
Desired Head in feet
Desired Gallons
per minute (GPM)
Desired Revolutions
per minute (RPM)
Desired diameter of
impeller in inches
Desired Brake
Horsepower (BHP)
Capacity varies directly as the speed or diameter:
G2 = G1 (R2/R1) or G2 = G1 (d2/d1)
Example Speed Change: 100 GPM x (3500 RPM / 1750 RPM) = 200 GPM
Example Diameter Change: 100 GPM x (6 in / 5 in) = 120 GPM
Head varies as the square of the speed or diameter:
H2 = H1 (R2/R1)2 or H2 = H1 (d2/d1)2
Example Speed Change: 50 ft. head x (3500 RPM / 1750 RPM)2 = 200 ft head
Example Diameter Change: 50 ft. head x (6 in / 5 in)2 = 72 ft head
Horsepower varies as the cube of the speed or diameter:
P2 = P1 (R2/R1)3 or P2 = P1 (d2/d1)3
Example Speed Change: 9 HP x (3500 RPM / 1750 RPM)3 = 72 HP
Example Diameter Change: 9 HP x (6 in / 5 in)3 = 15.6 HP
Specific Gravity Effect
Specific gravity affects the output pressure of a pump. The heavier the liquid, the more force will be required
to pump at the same performance. Brake horsepower varies directly with specific gravity. If the liquid has
specific gravity other than water (1.0), mutiply the brake horsepower for water by the specific gravity of the liquid
to be handled.

Definitions
NET POSITIVE SUCTION HEAD
NPSH stands for Net Positive Suction Head. It is defined as the suction gage reading in feet absolute taken on the
suction nozzle corrected to pump centerline, minus the vapor pressure in absolute corresponding to the temperature
of the liquid, plus velocity head at this point. When boiling liquids are being pumped from a closed vessel NPSH
is the static liquid head in the vessel above the pump centerline minus entrance and friction losses. See NPSH
example on pg. 11.
SPECIFIC GRAVITY
Specific gravity is the ratio of the weight of any volume to the weight of an equal volume of some other substance
taken as a standard at stated temperatures. For solids or liquids the standard is usually water, and for the gasses,
the standard is air or hydrogen.
STATIC HEAD
Static head is the vertical distance between the free level of the source of supply and the point of free discharge, or
to the level of the free surface of the discharge liquid.
SUCTION LIFT
Suction lift exists when the suction measured at the pump nozzle and corrected to the centerline of the pump is
below atmospheric pressure.
Static suction lift is the vertical distance from the free level of the source of supply to centerline of pump.
Dynamic suction lift is the vertical distance from the source of supply when pumping at required capacity, to
centerline of pump, plus velocity head, entrance, and friction loss, but not including internal pump losses, where
static suction head exists but where the losses exceed the static suction head. The dynamic suction lift is the sum of
the velocity head, entrance, friction, minus the static suction head, but not including internal pump losses.
Dynamic suction head, as determined on test, is the reading of the mercury column connected to suction nozzle
of pump, plus vertical distance between point of attachment of mercury column to centerline of pump, plus head of
water resting on mercury column, if any.
TOTAL DYNAMIC HEAD (TDH)
Total dynamic head is the vertical distance between source of supply and point of discharge when pumping at
required capacity, plus velocity head, friction, entrance and exit losses.
Total dynamic head, as determined on test where suction lift exists is the reading of the mercury column connected
to the suction nozzle of the pump plus the reading of a pressure gage connected to discharge nozzle of pump plus
vertical distance between point of attachment of mercury column and center of gage, plus excess, if any, of velocity
head of discharge, over velocity head of suction, as measured at points where the instruments are attached, plus
head of water resting on mercury column, if any.
Total dynamic head, as determined on tests where suction head exists, is the reading of the gage attached to the
discharge nozzle of pump minus the reading of a gage connected to the suction nozzle of pump, plus excess,
if any, of the velocity head of discharge over velocity head of suction as measured at points where instruments
are attached.
Total dynamic discharge head is the total dynamic head minus dynamic suction lift, or plus dynamic suction head.

Definitions
SUCTION HEAD
Suction head (sometimes called head of suction) exists when the pressure measured at the suction nozzle and
corrected to the centerline of the pump is above atmospheric pressure.
Static suction head is the vertical distance from the free level of the source supply to centerline of pump.
Dynamic suction head is the vertical distance from the source of supply, when pumping at required capacity, to
centerline of pump, minus velocity head, entrance, friction, but not minus internal pump losses.
Dynamic suction head, as determined on test, is the reading of a gage connected to suction nozzle of pump, minus
vertical distance from center of gage to centerline of pump. Suction head, after deducting the various losses, may
be a negative quantity, in which case a condition equivalent to suction lift will prevail.
VELOCITY HEAD
The velocity head (sometimes called “Head due to velocity”) of water moving with a given velocity, is the equivalent
head through which it would have to fall to acquire the same velocity; or the head necessary merely to accelerate
the water. Knowing the velocity, we can readily figure the velocity head from simple formula:
h=
V2
2g
in which g is accelaration due to gravity, or 32.16 feet per second; or knowing the head, we can
transpose the formula to:
V=
2gh
and thus obtain the velocity.
The velocity head is a factor in figuring, the total dynamic head, but the value is usually small, and in most cases
negliglibe; however, it should be considered when the total head is low and also when the suction lift is high.
Where the suction and discharge pipes are the same size, it is only necessary to include in the total head the
velocity head generated in the suction piping. If the discharge piping for computing the velocity head rather than the
velocity in the suction pipe.
Velocity head should be considered in accurate testing also, as it is part of the total dynamic head and consequently
affects the duty accomplished.
In testing a pump, a vacuum gage or a mercury column is generally used for obtained dynamic suction lift. The
mercury column or vacuum gage will show the velocity head combined with entrance head, friction head, and static
suction lift. On the discharge side, a pressure gage is usually used, but a pressure gage will not indicate velocity
head, and this must, therefore, be obtained either by calculating the velocity, or taking readings with a pitometer, to
take a number of readings at different points in the cross section.
A table, giving the relation between velocity and velocity head is shown below:

VISCOSITY
Viscosity is the internal friction of a liquid tending to reduce flow.
Viscosity is ascertained by an instrument termed a viscosimeter, of which there are several makes. With few
exceptions, viscosity is expressed as the number of seconds required for a definite volume of fluid under an
arbitrary head to flow through a standardized aperture at constant temperature.

General Information
STATIC PRESSURE
FRICTION FACTOR PIPE SIZING FORMULA
One foot of elevation change results in a change in
static pressure of .433 psi. Dynamic Pressure in a
piping system (when water is flowing) varies according
to these following five factors, but is always less than
static pressure for that same point.
1. Velocity (of water-normally measured in ft. per sec.)
2. Inside Diameter (of pipe)
Ff =
Po x Pv
Lc
Ff = Allowable psi loss per 100” of pipe
Po = Operating pressure of sprinkler
Pv = Allowable percentage pressure variance
Lc = Longest run of lateral line (critical length)
3. Roughness (of inside wall of pipe)
4. Length (of pipe)
5. Change of Direction (such as elbows and tees)
Note: This does not include remote control valves,
backflow prevention devices, etc. The
manufacturer’s performance charts must be
consulted for pressure loss information.
This formula is used to determine the allowable
pressure loss per 100” of lateral pipe. Multiplying the
operating pressure by the percentage variation and
dividing that number by the longest run of pipe from
the control valve to the farthest head (divided by 100”
length) gives us a guideline by which each section of
pipe can be sized.
Note: We recommend 10% as an acceptable operating
pressure variation within a lateral line.
PIPE SIZING
Two methods used to determine the pipe sizing are
the velocity limit method which is recommended for
main line sizing and the friction factor method for
sizing laterals.

VELOCITY LIMIT PIPE SIZING FORMULA
Velocity of flow values is computed using the
general equation:
V = .408
Q
d2
V = Velocity in feet per second
Q = Flow Volume (GPM)
d = Inside diameter of pipe
Atmospheric pressure at sea level is 14.7 lb/in2. This
pressure with a perfect vacuum will maintain a column
of mercury 29.9 inches or a column of water 33.9 feet
high. This is the theoretical distance that water may be
drawn by suction. In practice, however, pumps should
not have a total dynamic suction lift greater than 25 feet.
