Ehe exhaust heat of around 600oc is used in a heat recovery process to generate electricity through a steam turbine, with a low temperature (after the condenser) of around 40oc. given the utilization efficiency of 0.45 applies to the carnot efficiency for this second conversion process, what is the overall process efficiency, using the realistic efficiency of 0.4 for the gas turbine based process (combined cycles)?

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
