Consider a Rankine cycle with a single regenerative feed-water heater. The steam enters the turbine at 30 bar 400C and the condenser pressure is 0.1 bar. The feed-water heater is a direct contact type and operates at a pressure of 5 bar. Determine: a. The cycle efficiency b. The mean temperature of heat addition c. Compare the results for part (a) and (b) for the case of Rankine cycle without regeneration.
