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.

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

Try a technical library.

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