At the gasoline transfer facility (ρᵣₑₗ=0,75) from the pond of

 storage to consumption, you want to install a pump to circulate a flow of 40(lt/s). The 400m long pipe is cast iron 150mm in diameter and consists of

 a check valve, a gate valve and 2 commercial medium radius elbows. The

 consumption tank is pressurized to 2,9 (kgf/cm²) gauge pressure. Decide

 the drive power of the pump in KW if its performance is 70%.

•Additional data, pressure drop factors:

•Retention valve Kᵣ = 1,5

•Gate valve open Kᵥ = 0,21

•Medium Radius Commercial Elbow Kc = 0,75 for each cubit

•Storage pond outlet sharp angles Kₛ = 0,5

•Entrance to consumption pond Kₑ = 1

•Friction factor in pipes f = 0.026
