Question

(15) Steam enters the turbine shown in the figure. The steam flows steadily and leaves as saturated liquid-vapor mixture. Assume steady state operation and ignore kinetic and potential energy effects. STATE DATA FOR TURBINE $(Av)_1 = 1.5 \text{ m}^3/s$ P1 = 20 bar T1 = 485 $^\circ$C P2 = 0.6 bar x2 = 0.90 A. What is the mass flow rate through the turbine in kg/s? B. With perfect insulation around the turbine, calculate the power output in kW. C. Suppose that the insulation is removed and heat transfer occurs from the turbine to its surroundings at a rate of 200kW. Calculate the power output for this situation.
