Jennifer is a Mechanical Engineer, and is hired to design a massive 450 MW power plant for the city of Dubai. Jennifer decides that the optimal efficiency would be obtained if the pressure of saturated vapor entering the turbine should be 10 MPa, and the pressure of saturated liquid exiting the condenser to be 0.005 MPa.  Dubai is in the United Arab Emirates (UAE), where the water from the Persian Gulf is 40 °C and UAE environmental laws limit the exiting cooling water to a maximum temperature of 45 °C (in order to prevent damage to the local fishing industry).  For Jennifer’s power plant, calculate:   heat input form the boiler (in Mega Watts) thermal efficiency mass flow rate of cooling water (in kg/s)
