Crude oil (î¼ = 40 cp, sg = 0.87) is to be pumped from a storage tank to a refinery through a series of pump stations via 10-in, schedule-20, commercialsteel pipeline at a flowrate of 2000 gpm. the pipeline is 50 mi long and contains 35 90â° elbows and 10 open gate valves. the pipeline exit is 150 ft higher than the entrance, and the exit pressure is 25 psig. what horsepower is required to drive the pumps if they are 70% efficient?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
