2. (45 points) In class, we developed the system of equations for a regenerative Rankine cycle using a closed feedwater heater with a pump to allow mixing of the feed (bleed) stream of water to occur at a higher pressure. Then there is also the case where a trap or throttling valve can be used to allow mixing to occur at a lower pressure (see below). Consider a regenerative Rankine cycle using a closed FWH, where the feedwater stream exits as a saturated liquid. The pump and turbine efficiencies are given as 86% and 92%, respectively. The turbine inlet is at 6 MPa and 800°C, and the condenser operates at 50 kPa. 10% of the total steam is extracted at 1.5 MPa to serve the closed FWH, which discharges into the condenser after being throttled to condenser pressure. Water exits the condenser as a saturated liquid. Neglect pressure changes across the boiler/condenser. P = 6 MPa T = 800°C η = 92% Boiler P = 1.5 MPa x₇ = 0 Closed FWH Condenser η = 86% Pump x₁ = 0 (a) (20 points) Determine the pressure, temperature, quality, enthalpy, and entropy for all 8 states in the cycle. Submit your answer in array form. (b) (5 points) If the cycle requires a net power output of 5 MW, determine the mass flow rate of water through the boiler. (c) (5 points) Determine the mass flow rate of water extracted from the turbine to serve the FWH. (d) (5 points) Determine the cycle thermal efficiency. (e) (10 points) If the boiler operates at a temperature equivalent to the maximum temperature in the cycle, and the condenser rejects heat to an ambient environment of 20°C, determine the second law efficiency of this cycle.
