Q: Reconsider Prob. 6–43. Using appropriate software, investigate
Reconsider Prob. 6–43. Using appropriate software, investigate the effect of the turbine exit pressure on the power output of the turbine. Let the exit pressure vary from 10 to 200 k...
See AnswerQ: Steam flows steadily through a turbine at a rate of 45,
Steam flows steadily through a turbine at a rate of 45,000 lbm/h, entering at 1000 psia and 900°F and leaving at 5 psia as saturated vapor. If the power generated by the turbine is 4 MW, determine the...
See AnswerQ: Steam enters an adiabatic turbine at 8 MPa and 500°C
Steam enters an adiabatic turbine at 8 MPa and 500°C at a rate of 3 kg/s and leaves at 20 kPa. If the power output of the turbine is 2.5 MW, determine the temperature of the steam at the turbine exit....
See AnswerQ: Carbon dioxide enters an adiabatic compressor at 100 kPa and 300 K
Carbon dioxide enters an adiabatic compressor at 100 kPa and 300 K at a rate of 0.5 kg/s and leaves at 600 kPa and 450 K. Neglecting kinetic energy changes, determine (a) the volume flow rate of the c...
See AnswerQ: Steam flows steadily into a turbine with a mass flow rate of
Steam flows steadily into a turbine with a mass flow rate of 26 kg/s and a negligible velocity at 6 MPa and 600°C. The steam leaves the turbine at 0.5 MPa and 200°C with a velocity of 180 m/s. The rat...
See AnswerQ: Air is compressed by an adiabatic compressor from 100 kPa and 20
Air is compressed by an adiabatic compressor from 100 kPa and 20°C to 1.8 MPa and 400°C. Air enters the compressor through a 0.15-m2 opening with a velocity of 30 m/s. It exits through a 0.08-m2 openi...
See AnswerQ: The ventilating fan of the bathroom of a building has a volume
The ventilating fan of the bathroom of a building has a volume flow rate of 30 L/s and runs continuously. If the density of air inside is 1.20 kg/m3, determine the mass of air vented out in one day.
See AnswerQ: Air enters the compressor of a gas-turbine plant at ambient
Air enters the compressor of a gas-turbine plant at ambient conditions of 100 kPa and 25°C with a low velocity and exits at 1 MPa and 347°C with a velocity of 90 m/s. The compressor is cooled at a rat...
See AnswerQ: A portion of the steam passing through a steam turbine is sometimes
A portion of the steam passing through a steam turbine is sometimes removed for the purposes of feedwater heating as shown in Fig. P6–51. Consider an adiabatic steam turbine with 12....
