A steam power plant that operates on a simple ideal Rankine cycle, the boiler pressure is 2 MPa and the condenser pressure is 10 kPa. The maximum temperature in the cycle is 400°C. Determine the thermal efficiency, a) of the given cycle, b) if the maximum temperature of the simple cycle has increased to 600°C. For both cases, show the cycle on the T-s diagram with respect to saturation lines and interpret the property changes in the turbine output by the modifications.
