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 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_forward
