1. A steam power plant has 4 MPa, 500?C into the turbine, and to have the condenser itself deliver the process heat, it is run at 101 kPa. How much net power as work is produced for process heat of 13 MW?

2. Steam must be generated at 150?C for process heat in a food production facility. This is done in a combined heat and power system as extraction steam from the turbine. Assume the standard cycle has a turbine inlet of 3 MPa, 450?C and 60?C in the condenser. What pressure should be used for the extraction so that a maximum of process heat at 150?C is available and the least amount of turbine work is lost?
