Determine the electrical power supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 150000 W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. Calculate the total rate of entropy production. Calculate the total rate of exergy destruction (W) The dead state temperature is 293.2 K and pressure is 1 bar.
