5. Hydroelectric power facilities are useful ways of generating renewable energies. Within a dam the water is walled off and creates a reservoir behind a river. Water is released from the reservoir and it flows downwards as it passes through turbines to generate electricity. The hydrostatic force of the reservoir acting on the dam wall is important to know when designing the system. Due to the linear nature of the pressure acting on the dam wall we can assume that the pressure acting on the entire wall is the midpoint of the dam (i.e. half way down the height of the dam).

a. The Zukes dam is 210 feet high and 11,300 feet wide, what is the force (in psi) acting on the dam wall? Remember to account for atmospheric pressure. *for pressure use the hydrostatic equilibrium equation*
