You are an entry level engineer in charge of keeping water balance in a water dam which is connected by a pipe to a city.The dam is a 82,02.5 ft by 13,124 ft rectangle. Flow is assumed unsteady and velocity is uniform. Uniform velocity is 8 ft/s. Pipe diameter is 7.5 ft. Density of air is 1.23 kg/m^3 and density of water is 1,000 kg/m^3. what is the law of mass conservation for this situation if air at control surface 1 is neglected.
