An ideal Rankine cycle operates between the pressure limits of 6 bar and 0.1 bar with steam as the working fluid (data above). Saturated water leaves the condenser and the turbine inlet temperature is 250°C. You may assume that the work input to the boiler feed water pump is negligible. Estimate the efficiency of the cycle and determine the turbine power in kJ/kg.
