A steam turbine, as shown in Figure Q3, operates at steady state with inlet conditions of Pi= 2 MPa, T1 = 480°C and producing 4000 kW. Saturated steam leaves the turbine at a pressure of 0.1 bar where it is condensed at 45.81 °C in the condenser. There is no significant heat transfer between the turbine and the condenser and their surroundings, and kinetic and potential energy changes between inlet and exit are negligible.

Steam enters the first-stage turbine shown in Fig. P4.50 at 40 bar and 500℃
Steam enters the first-stage turbine shown in Fig. P4.50 at 40 bar and 500℃ with a volumetric flow rate of 90 m3/min. Steam exits the turbine at 20 bar and 400℃. The steam is then reheated at constant pressure to 500℃ before entering the second-stage turbine. Steam leaves the second stage as saturated vapor at 0.6 bar. For operation at steady state, and ignoring stray heat transfer and kinetic and potential energy effects, determine the(a) mass flow rate of the...
