The diagram shows a cross-section through a dam used for storing liquid.
The dam is 12m wide.
(a) Calculate the centre of pressure of the liquid in
contact with the dam wall. The liquid has a relative density of 1.023 compared to fresh water.
(b) Calculate the density of the liquid. Assume the density of fresh water is 1000 kg/m³. (c) Calculate the hydrostatic thrust on the dam wall. Calculate the overturning moment due to the liquid.
