The pump adds power to the water flowing from the lower reservoir. Find the horsepower added if the flow through the system is 400 m^3/s. The entrace is sharp, the two bends are equivalent to smooth 90 degree bends with R=1 ft, and there are two fully open gate valves ( one on each side of the pump) in the system. Reservoir one is at an elevation of 175 meters and reservoir two is at 150 meters the pip is 4 meters in diameter.
