Problem 2. Steam generated in a power plant at a pressure of 8MPa and a temperature of 470C is fed to a turbine shown in Figure 1. Exhaust from the turbine enters a condenser at 10kPa, where it condenses to saturated liquid, which is then pumped to the boiler. (a) Find the heat transfer rates in the boiler and condenser then calculate the thermal efficiency of a Rankine cycle operating at these conditions? (b) What is the thermal efficiency of a practical cycle operating at these conditions if the turbine efficiency and pump efficiency are both 0.8 ? (c) If the rating of the power cycle of part (b) is 97000kW, what is the steam rate in kg/s
