2. Steam enters an adiabatic turbine at 4.5MPa and 350°C and leaves at 225kPa with a quality of 85 percent. Neglecting the changes in kinetic and potential energies, determine the mass flow rate required for a power output of 700kW.
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...
