- (read image) Answer:arrow_forwardThe correct answer is ~168 MPa, how was this found?arrow_forwardAir enters the compressor of a regenerative gas turbine engine at 310 K and 100 kPa, where it is compressed to 900 kPa and 650 K. The regenerator has an effectiveness of 75%, and the air enters the turbine at 1400 K. Assume variable specific heats for air. For a turbine efficiency of 90 percent, determine the amount of heat transfer in the regenerator. The amount of heat transfer in the regenerator is kJ/kg.arrow_forward
- Air enters the compressor of a regenerative gas turbine engine at 310 K and 100 kPa, where it is compressed to 900 kPa and 650 K. The regenerator has an effectiveness of 79 percent, and the air enters the turbine at 1400 K. Assume constant specific heats for air at room temperature. The properties of air at room temperature are cp = 1.005 kJ/kg·K and k = 1.4. For a turbine efficiency of 90 percent, determine the amount of heat transfer in the regenerator. The amount of heat transfer in the regenerator is kJ/kg.arrow_forwardHints: Find the closed loop transfer function and then plot the step response for diFerentvalues of K in MATLAB.
