Extracted text: Problem 4: Consider the following schematic of a simple turbojet engine model that uses air as its working fluid. With the data given determine (A) the pressure and temperature of all five states, (B) the amount of heat added in the burner, (C) the necessary air-to-fuel ratio of the engine, (D) the amount of power required by the compressor, and (E) the velocity of the exhaust stream at the exit of the system. Note: The variable rp is the compressor ratio defined to be the pressure of the compressor exit to the pressure of the compressor inlet. Assume that the compressor, turbine, and nozzle are all adiabatic and reversible. The Turbojet Engine 2 P = Pj : 100 kPa Burner T,: 300 k 6: 12 5= 1200 K FHV = 43 KJ/g- frel
