need help fast please
A pump takes water at 70F from a large reservoir and delivers it to the bottom of an elevated pressurized tank (P= 15 psig) through a 2.5-in Schedule 40 pipe. The inlet to the pump is located 6 ft above the water surface in the reservoir, and the water level in the tank is constant at 140 ft above the reservoir surface. The suction line consists of 80 ft of 2.5-in Schedule 40 pipe with two 90 elbows and one gate valve, while the discharge line is 230 ft long of 2.5-in Schedule 40 pipe with four 90 elbows and two gate valves. A venturi meter with a 1.5-in throat diameter connected to a mercury manometer is installed in the line to measure the flow rate. The reading in the manometer is 6 in. (a) What is the flow rate in gal/min? (b) Calculate the brake horsepower of the pump if efficiency is 65% (c) Calculate the NPSH Step by Step Solution
