# Question: dam is 11m high and the pepth of the valve...

###### Question details

Dam is 11m high. And the pepth of the Valve is 10m deep.

 Parameter Symbol Value Units Height of dam HDam 11 m Height of water above middle of Pipe A H 10 m Height to middle of Pipe A from the datum Z1 150 m Height to middle of Pipe B from the datum Z2 50 m Height to edge of Pipe C from the datum Z3 0 m

At the initial design phase, the dam of Reservoir 1 (Dam 1) was suggested to be a simple gravity dam with a rectangular cross-section built from concrete, with a density of 2,350 kg/m3. When the reservoir is full, the water level and the top of the dam wall are at the same height.

a)      Determine the hydrostatic force on a unit width (1 m) of dam wall when the dam is operating at its maximum capacity (when the reservoir is full).

b)      Determine the minimum dam wall thickness by applying the “middle third rule” assuming a unit width of dam for calculation. Include uplift as a hydrostatic pressure distribution acting vertically upwards on the base.
