Steam enters a turbine operating at steady state at 2 MPa, 360 °C with a velocity of 52 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 35 m/s. The elevation of the inlet is 1 m higher than at the exit. The mass flow rate of the steam is 21 kg/s, and the power developed is 5 MW. Let g = 9.81 m/s2. Determine the area at the inlet, in m2.

Problem-1 (200) A power plant with a mass flow rate of 281.8 Kg/s operates on a regenerative vapor power cycle with one open feed-water heater. Steam enters the first turbine stage at 14 MPa, 600°C and expands to 2 MPa, where some of the steam is extracted and diverted to the open feed-water heater operating at 2 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 8 kPa. Saturated liquid exits the open feed-water...

As shown below, steam at 80 bars (8 MPa) and 450 degrees Centers a well-insulated turbine operating at steady state with a volumetric flow rate of 236 m/min. Twenty percent of the entering mass flow exits through a pipe of diameter 0.25 m at 60 bars (6 MPa) and 400 degrees C. The rest exits through a pipe of diameter 1.5 m with...
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...
