Question details

Problem Review of the Steady-State Macroscopic Energy and Entropy Balances. Consider a Rankine power cycle with reheat for production of electricity as shown in the process flow diagram below: 3 Turbine Turbine 0Boiler #1 #2 4 5 1 Pump Condenser Qc The first turbine has superheated steam entering at {T, = 480°C and B-80bar. The steam expands to a pressure of [P-15bar) in the first turbine, undergoes reheat to (T,-480 C) and then expands again in the second turbine to P 8kPa . Estimate the amount of steam required in MMSCFD in order to generate 80MW of power if the efficiency of the turbines is 88% and the efficiency of the p 2. Calculate the thermal efficiency of the cycle. . Calculate the amount of power rejected as heat 4. If cooling water is available at 35 degrees Celsius calculate the amount of water in GPM ump is 8 0% required for the condenser. Assume a water temperature rise of 15 degrees Celsius.
