2.) A tank is in the shape of a frustum of a pyramid having a square section. The upper base is 3.0m x 3.0m, and the lower base is 1.5m x 1.5m with a height of 3.0m. determine the time required to lower down the water surface 2.0m through a 10cm by 10cm square orifice located at the bottom. Assume the tank to be initially full of water and use C=0.60.
