Required information Problem 09.112 - Brayton Cycle with Regeneration using Variable Specific Heats - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS A Brayton cycle with regeneration using air as the working fluid has a pressure ratio of 7. The minimum and maximum temperatures in the cycle are 310 and 1150 K. Assume an isentropic efficiency of 75 percent for the compressor and 82 percent for the turbine and an effectiveness of 67 percent for the regenerator. Use variable specific heats for air. Problem 09.112.c - Thermal Efficiency Brayton Cycle with Regeneration Determine the thermal efficiency. The thermal efficiency is 1%.
