Energy Conversion Review problems: 1. Air is compressed in a piston-cylinder with a compression ratio of 7:1. If the initial condition is 37C,1 atm and 1L and the process is frictionless and adiabatic, what is the final temperature, pressure, and volume? 2. Estimate the gas temperature entering the combustor of a gas turbine that has a compressor operating with a pressure ratio of 20:1 at standard ambient conditions. How much heat would one need to remove to match the gas temperature going into the combustor if the pressure ratio was 40:1
