A water intake at a pump storage reservoir (see the figure below) has a cross-sectional area of 0.637 m. The water flows in at a speed of 0.470 m/s. At the generator building, at distance D = 156 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.44 m/s. What is the difference in pressure between inlet and outlet? Reservoir Number i 202.6 Units MPa Generator building Intake Outlet
