An open-topped tank completely filled with water has a release valve near its bottom. The valve is h = 1.9 m below the water surface. Water is released from the valve to power a turbine, which generates electricity. The area of the top of the tank, A_T, is 38 times the cross-sectional area, A_V, of the valve opening.
(1) Calculate the speed of the water as it exits the valve. Neglect friction and viscosity.
(2) Calculate the speed of a drop of water released from rest at h = 1.9 m when it reaches the elevation of the valve.
