    Need help for A, B, and C, thanks. 1. an electrical power plant has an overall efficiency of 15%. The plant is to deliver 150 MW of electrical power to a city, and it turbines use coal as fuel. The burning coal produces steam at 190 C, which droves the turbines. The steam is condensed into water at 25C by passing through coils that are in contact with river water. Note: the heat of combustion of coal is 7.8 X...

    1. Exhaust gas at 400 C and 1 bar from i engines flows at the rate of 125 mol s into a waste-heat boiler where saturated steam in generated at a pressure of 1200 kPa. Water enters the boiler at 20 C (Ta) and the exhaust gases are cooled to within 10°C of the steam temperature. The heat capacity of the exhaust gases is C/R-3.341.12x10 T/K. The steam flows into an adiabatic turbine and exhausts at a pressure of 25...
