A single shaft gas turbine engine receives air at atmospheric conditions of 14.7 psia and 80 degrees F. The compressor discharge pressure is 103psia and the compressor efficiency is 87%. The turbine inlet temperature is 1980 degrees F and the exhaust temperature is 1173 degrees F. Assume a 3 psi pressure drop in the combustion chamber and that inlet and exhaust ducts losses are both 27.7 inches of water. Find: a) Sketch the system and label the state point locations b) Draw the h-s graph for the cycle c) Complete an entire state point table to include p(psia), T(deg F), h (Btu/lbm), and the process at each state d) calculate the compressor pressure ratio e) Calculate the isentropic efficiency of the turbine f) Calculate the thermal efficiency of the engine
