3. You’ve developed a cold air standard Brayton cycle with a heat input from combustion of 5.0 x 106 Btu/h. Air enters the turbine at 2800°R and exits at 520°R, and the cycle has a compressor-pressure ratio of 12. If the specific heat is evaluated at 520°R, and the turbine and compressor both have isentropic efficiencies of 95%, what is the net power developed by the cycle, in hp?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
