- Water is being pumped from a reservoir to the top of a hill, where it is discharged, as shown in Fig. 20-21. Thepump, which is 70 percent efficient, is rated at 150 kW. Find the flow rate at which water is being dischargedfrom the pipe. Neglect minor losses.arrow_forwardIn a water Transfer installation, from the storage tank to the consumption tank, a pump is to be installed to circulate a flow rate of 60 lt/s. The 380 meter long Pipe is Made of cast iron of 150 mm diameter and consist of a check valve, a gate valve and 3 commercial elbows of medium Radius.The consumir tank is pressurized to 3.5 Kgf/cm2 gauge pressure.Determine the driving power of the KW pump if it's efficiency is 73%.
