Problem 1 (25 points) - Simple Rankine Cycle Consider a simple, ideal Rankine cycle using water as the working fluid. Steam exits the turbine as a saturated vapor, and heat is transferred to the steam at a rate of 36 MW in the boiler. Further operating data is given below. . Turbine: P. = 6 MPa, P = 7.5 kPa in out . The steam is cooled by water from a nearby river that enters the condenser at 17 C. The steam leaves the condenser as a saturated liquid. a) Show the cycle on a T - s diagram. b) Determine the turbine inlet temperature. c) Determine the net power output and the thermal efficiency of the cycle. d) Determine the minimum mass flow rate of cooling water required for this cycle. (Hint: The minimum mass flow rate of the cooling water would result in the maximum outlet temperature of the cooling water from the condenser.)
