As shown in the figure below, water behind a dam enters an intake pipe at a pressure of 24 psia and velocity of 5 ft/s, flows through a hydraulic turbine-generator, and exits at a point z1 = 120ft below the intake at 19 psia, 45 ft/s, and a specific volume of 0.01602 ft/lb. The diameter of the exit pipe is 5 ft and the local acceleration of gravity is 32.2 ft/s?.

As shown in the figure below, water behind a dam enters an intake pipe at a pressure of 24 psia and velocity of 5 ft/s, flows through a
hydraulic turbine-generator, and exits at a point z1 = 120ft below the intake at 19 psia, 45 ft/s, and a specific volume of 0.01602 ft/lb.
The diameter of the exit pipe is 5 ft and the local acceleration of gravity is 32.2 ft/s?.
