Niagara Falls is capable of producing a total power output of 2.575 MW at steady-state during the night when flow over the falls is diverted through a hydroelectric turbine. This is done at night so as not to detract from tourism during the daytime. Changes in temperature and pressure of the flow through the turbine are negligible. The intake to the turbine is located at the top of Niagara River and exits at the bottom of the falls, 22 m below. The velocity of the water in the penstock upstream of the turbine is, on average, 0.6 m/s and exits the turbine, operating adiabatically, at 0.9 m/s. - What is the mass flow rate of water through the turbine at night, in kg/s?
