Air at 10 degree C and 80 kPa enters the diffuser of a jet engine steadily with a velocity of 200 m/s. The inlet area of the diffuser is 0.4 m^2.The air leaves the diffuser with a velocity that is very small compared with the inlet velocity. Determine the mass flow rate of the air and the temperature of the air leaving the diffuser. Air at 100 kPa and 280 K is compressed steadily to 600 kPa and 400 K....
Steam flows steadily through an adiabatic turbine
Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s, and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Determine a. (3) Change in kinetic energy (-23.4 kJ) b. (4) Power output (12.12 MW) c. (3) Turbine inlet area (0.012966 m2)

In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...

01: Steam enters the first turbine at 15.0 MPa and 600°C. The pressure in the condenser is 20.0 kPa. While some steam is extracted from the high-pressure turbine at 5 MPa and sent to the closed feedwater heater, the remaining steam is reheated to 600°C. The extracted steam is condensed as saturated liquid at 5.0 MPa and trapped to the open feedwater heater. Some steam is extracted from the lower-pressure turbine at 1.0 MPa and sent to the open feedwater...
