4. The inlet steam to an extraction turbine is 30 bara and 400C. The extraction steam is at 10 bara and the exhaust is condensed at 0.12 bara. The steam turbine is fully loaded with a throttle flow of 40 kg.s=1 to the inlet, 15 kg.s-' going to extraction and the remaining 25 kg.s- going to condensation. Using the Willans' Line Model with parameters for large back-pressure and condensing turbines from Table 23.1 and an intercept ratio of 0.05, calculate the power production. 4.
