Question
### Required Information for Regenerative Gas Turbine Engine 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 78 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: - \( c_p = 1.005 \, \text{kJ/kg}\cdot \text{K} \) - \( k = 1.4 \) #### Problem Statement For a turbine efficiency of 90 percent, determine the amount of heat transfer in the regenerator. (You must provide an answer before moving on to the next part.) The amount of heat transfer in the regenerator is: \(\_\_\_\_\_\_\_\_\_\_\_\_\_\)_ kJ/kg.
