A W A Standard
This document is an American Water Works Association (AWWA) standard. It is not a specification.
AWWA standards describe minimum requirements and do not contain all of the engineering and
administrative information normally contained in specifications. The AWWA standards usually con-
tain options that must be evaluated by the user of the standard. Until each optional feature is
specified by the user, the product or service is not fully defined. AWWA publication of a standard
does not constitute endorsement of any product or product type, nor does AWWA test, certify, or ap-
prove any product. The use of AWWA standards is entirely voluntary. AWWA standards are in-
tended to represent a consensus of the water supply industly that the product described will
provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of
action will be placed on the first page of the classified advertising section of Journal AWWA. The
action becomes effective on the first day of the month following the month of Journal AWWA publi-
cation of the official notice.

American National Standard
An American National Standard implies a consensus of those substantially concerned with its scope
and provisions. An American National Standard is intended as a guide to aid the manufacturer, the
consumer, and the general public. The existence of an American National Standard does not in any
respect preclude anyone, whether he has approved the standard or not, from manufacturing,
marketing, purchasing, or using products, processes, or procedures not conforming to the standard.
American National Standards are subject to periodic review, and users are cautioned to obtain the
latest editions. Producers of goods made in conformity with an American National Standard are en-
couraged to state on their own responsibility in advertising and promotional materials or on tags or
labels that the goods are produced in conformity with particular American National Standards.

CAUTION NOTICE: The American National Standards Institute (ANSI) approval date on the front
cover of this standard indicates completion of the ANSI approval process. This American National
Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken
to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.
Purchasers of American National Standards may receive current information on all standards by
calling or writing the American National Standards Institute, Inc., 1430 Broadway, New York, NY
10018 (212) 354-3300.

A-6.11.5 The bowl assembly input power PI , in horsepower, to a pump driven
by an electric motor is

kW
0.746

P1 = Eg

Where:

kW = corrected kilowatt input to motor
E g = motor efficiency from the calibration curve

A-6.11.6 The pump-bowl assembly efficiency E1 is

Qhl E1 =
3960 x ( P I )

Where:

Q = measured capacity, in gallons per minute
hl = bowl assembly head, including velocity head, in feet
P1 = brake horsepower to the pump bowl assembly, measured by

dynamometer or calibrated motor

NOTE: gpm x 0.2271 = m3k; f t x 0.3048 = m; hp x 0.746 = kW.

A-6.11.7 The pump total head H , in feet, is found by

Where:

hl = bowl assembly head from test, in feet
h c = column loss, in feet, obtained from Figure 3 and based on

complete pump setting
h e = discharge head loss, in feet, from Figure 4 or actual test

NOTE: f t x 0.3048 = m.

A-6.11.8 The pump input power, in horsepower, is found by

P = Pl + PC + Pt. (Eq 13)

Where:

P1 = bowl assembly input power, in horsepower, calculated from test,
as in Sec. A-6.11.3 or Sec. A-6.11.5

PC = line-shaft loss in power, in horsepower, obtained from Figure 5 and

Pt = thrust-bearing loss, in horsepower

NOTE: hp X 0.746 = kW.

based on complete pump setting

A-6.11.9 The pump efficiency Ep is found using the equation

&H
E p =

3960 x P (Eq 14)

in which the pump total head H, in feet (ft x 0.3048 = m), is obtained from Sec. A-
6.11.7 and the power input P, in horsepower (hp x 0.746 = kW), is obtained from
Sec. A-6.11.8.

A-6.11.10 The overall efficiency E is the pump efficiency Ep multiplied by the
driver efficiency Eg.

A-6.11.11 The complete pump total head, efficiency, and pump input power
should be plotted as ordinates on the same sheet against the capacity as abscissa to
show the anticipated field performance of the complete pumps.

Sec. A-6.12 Other Tests
For more complete tests or for tests involving fluids other than water refer to

Hydraulic Institute" test standards, as applicable.
