    Rankine cycle, saturated liquid water at 1 bar is compressed isentropically to 150 bar. First by heating in by superheating at constant pressure of 150 bar, the water substance is brought to 750°K After adiaba enerate ansion in a turbine to 1 bar, it is then cooled in a condenser to saturated liquid. What is the thermal efficient

    A back pressure steam turbine 66^{\circ}C KW serves as a prime mover in a cogeneration system. The boiler admits the eturn water at a temperature of and produces the steam at moMpa and 455^{\circ}C. Steam then enters a back pressure urbine and expands to the pressure of the process, which is 0.521 2 Assuming a he effect of pumping and the pressure drops boiler efficiency of 80% and neglecting sat various location, Mpais the incremental heat rate for electric The following enthalpies have been found; turbine entrance KJ/kg, exit = 2700.8; boiler entrance =276.23 KJ/kg =3306j
