Steam exits a turbine with a mass flow rate of 2x10^5 kg/h at a pressure of 0.008 MPa, quality of 94%, and velocity of 70 m/s. Determine the maximum theoretical power that could be developed by any one-inlet one-exit control volume at steady state, that would reduce the steam to the dead state at the exit while allowing heat transfer only at temperature To. The exergy reference environment is at To = 15 degrees C, MPa. Gravity is to be neglected.
an industrial water shutoff valve is designed to operate with 30 lb of effort force. The valve will encounter 200 lb of resistance force applied to a 1.5 in. diameter axle. what is the required wheel diameter to overcome the resistance force?
