thermo2 plz help, please provide step by step solution, thank you so much!
The university has decided to build a new steam (working fluid water) power cycle. The boundary temperatures arc 800 C and 150 C, respectively foe the hot and cold boundaries of the cycle where heat is added and rejected The turbine has an isentropic efficiency of 72.0%, inlet water conditions of 16.0 MPa and 720 C, and an exit pressure of 2.0 MPa. Although the turbine is not ideal, you may assume it to be perfectly insulated. Find the actual work output per unit mass from the turbine; Find the maximum possible work per unit mass output from the turbine. If the cycle is used only to produce power, find the second law efficiency of the cycle. The cycle lias the following conditions (1) the heat rejection from the condenser is 40% of the actual tuibine output work, and (2) the pump work input is 15% of the actual tuibine output work. The unit costs for heat transfer at the high and low temperature boundaries are equal. The capitol cost for all equipment and maintenance is $2,500 per kg of water. If the unit cost of the work produced by the turbine and work input for the pump is $300 per kJ/kg, find the unit cost for the heat transfer from the high temperature reservoir.Explanation / Answer
