	Multiply the volumetric flowrate by the pressure rise and divide by the efficiency. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	HP = ω × Q × H / 75 ×ξ Where; ω is water density = 1000 Kg / CU meter Q is pump discharge in Cubic meter /second H is total head In meter ξ is pump efficiency example : for water pump with discharge of 60 CU. meter per hour at a total head 40 meter HP = ω × Q × H / 75 ×ξ ω = 1000 Kg / Cu meter Q = 60 / 3600 =0.01667 Cu metre / second H = 40 m Consider pump efficiency 60 % HP = 1000 ×0.01667 × 40 × 100 / 75 × 60 = 14.8 HP __________________ don't tell me who are you , what do you know is enough.
