(1.1) Consider a 65 MW steam power plant operating on a regenerative Rankine cycle with one open feedwater heater operating at 1 MPa. Steam enters the turbine at 16 MPa and 560°C, with a condenser pressure of 8 kPa. Determine the mass flow rate of the steam (kg/h), and the mass of the cooling water (kg/ h), if the temperature rise in the cooling water is 10 °C. (set it to four (4) decimal places for consistency)
2) A steam power plant operates according to the simple ideal Rankine cycle. The pressure limits of the cycle are 9 MPa and 10 kPa, and the flow of water eirculating in the cycle is 60 kg/s. It is required that the moisture content of the steam at the turbine outlet does not fall below 90 percent. Accordingly, calculate (a) the lowest possible turbine inlet temperature, (b) the heat supplied to the cycle, and (c) the thermal efficiency of the cycle by showing the cycle on a T-s diagram with saturated vapor and saturated liquid curves,.
