An open system with only one inlet and one exit operates at steady state. Mass enters the system at a flow rate of 5 kg/s with the following properties: h = 3484 kJ/kg, s = 8.0871 kJ/kg-K and V = 20 m/s. At the exit the properties are as follows: h = 2611 kJ/kg, s = 8.146 kJ/kg-K and V = 25 m/s. The device produces 4313 kW of shaft work while rejecting some heat to the atmosphere at 25oC.
(a) Do a mass analysis to determine the mass flow rate at the exit.
(b) Do an energy analysis to determine the rate of heat transfer (include sign).
(c) Do an entropy analysis to evaluate the rate of entropy generation in the system's universe.
