Oren is hired to design a massive 450 MW power plant for the city of Dubai. Oren decides that the optimal efficiency would be obtained if the pressure of saturdted vapár entering the turbine should be 10 MPa.and the presJure of saturated liquid exiting the condensor to be 0.005 MPa. Dubai is in the United Arab Emirates (UAE), where the water from the Persian Gulf is 4O °C and UAE environmental laws limit the exiting coa ling water to a maximum temperature of 45°C (to prevent damage to local fishing industry). For Oren's power plant, calculate : A.) heat input from the boiler (in MegaWatts) B.) thermal efficiency C.) mass flow rate of caoling water (in k/s)
