A power generation system with a turbine and a generator is located at a dam, where the water falls from 124.896 m height to the turbine. Assuming turbines having 100% efficiency, what should be the flow rate of water (in kg/s) to produce 5.776 MW of power?

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
