Question 3: The steam power plant operates according to the simple ideal Rankine cycle and has a net output power of 45 MW. Steam enters the turbine at 7 MPa pressure and 500 °C temperature and is cooled at 10 kPa pressure in the condenser by flowing cooling water from a lake through the condenser pipes with a mass flow rate of 2000 kg/s. Show the cycle on a T-s diagram and: (a) thermal efficiency of the cycle. (b) global flow rate of steam. (c) Calculate the temperature rise of the cooling water.
