Unformatted text preview: 2700 K to 3000 K. We wish to determine if the use of microwave heating is cost effective. Consider a power plant that is producing 1 MW of electric power as it operates with a low temperature of 290 K. The electric power sells for and costs $0.04 per kW ⋅ hr, and the heat transfer from the high temperature reservoir costs $0.01 per kW ⋅ hr. To achieve the 300 K increase in combustion temperature, 50 kW of electric power must be used. Determine (a) maximum income per year the plant can generate without the microwave heating (b) maximum income per year the plant can generate with the microwave heating Problem 3 Steam enters the compressor with isentropic efficiency 0.7626 at 50 ° C and 0.01 MPa and exits at 800 kPa. Determine a.) the ideal work input (in kJ/kg) required b.) the actual work input (in kJ/kg) required c.) the exit temperature of the steam...
