A modern jet engine operates on a simple ideal Brayton cycle in which the air into the compressor is at 0.1 MPa, 10°C, and the pressure ratio across the compressor is 12:1. Air enters the engine at rate of 0.5 kg/s. Combustion adds heat at rate of 700 kW. Use constant specific heats for air at room temperature. Determine, a-) The maximum temperature in cycle b-) Net power output c-) Thermal efficiency

Steam in a piston-cylinder assembly undergoes a polytropic process, with n = 2, from an initial state where V₁ = 4.38600 ft³, p₁ = 400 lbf/in², and u₁ = 1322.4 Btu/lb to a final state where u₂ = 1036.0 Btu/lb and v₂ = 3.393 ft³/lb. The mass of the steam is 2.5 lb. Changes in kinetic and potential energy can be neglected. Determine the change in volume, in ft3, the energy transfer by work, in Btu, and the energy transfer by heat, in Btu.
