How to calculate BHP of reciprocating pump

How to calculate BHP of reciprocating pump

How to calculate BHP of reciprocating pump

(OP)
How to calculate BHP of reciprocating pump ? Any guy can give a formula or info?

RE: How to calculate BHP of reciprocating pump


From Pump Handbook by Karassik et al. McGraw-Hill, Section 3.1, Power Pumps.

In USCS units:

bhp = (Q×Ptd)÷(1714×μ)

Q = delivered capacity (including gases and solids) in gpm
Ptd = developed (differential) pressure, psi
μ = mechanical effy.

RE: How to calculate BHP of reciprocating pump

To obtain BHP, use delivered capacity in GPM ( RPM X Displacement per revolution X V.E.) with the following formula: BHP = GPM X Discharge PSI/1714 X Mechanical Efficiency   When the suction pressure exceeds 5% of the discharge pressure, determine the BHP as above and subtract the suction pressure BHP: Suction BHP = (GPM) X (Suction Pressure) X (M.E. less 3 percentage points) / (1714) Example : 10.3 GPM actual delivered capacity , 300 psi Suction, 700 psi Discharge   BHP = 10.3 X 700 / 1714 X .86  minus  10.3 X 300 X .83 / 1714  = 3.4 BHP

thanks above guys


Any one knows where i can get Pump Handbook by Karassik et al. McGraw-Hill ?????????? Electronic version  is best , which website I can get it ?????

RE: How to calculate BHP of reciprocating pump


Try a technical library.

RE: How to calculate BHP of reciprocating pump

Pump Handbook
by Igor Karassik, William C. Krutzsch, Warren H.Fraser and Joseph P. Messina (Editors) 2nd Edition
Mc-Graw Hill Book Co.
ISBN 0-07-033302-5

may be there is a newer version.
you can buy it on line

There is a good article on Reciprocating Pumps by Terry L. Henshaw, in the ChE issue of Sept. 21. 1981.
