9-11 Jet Porpulsion - Applied Thermodynamics A turbojet is flying with a velocity of 900 ft/s at an altitude of 20,000 ft, where the ambient conditions are 7 psia and 10°F. The pressure ratio across the compressor is 13, and the temperature at the turbine inlet is 2340 R. Assume ideal operation for all components and constant specific heats for air at room temperature. The properties of air at room temperature are cp = 0.24 Btu/lbm·R and k = 1.4. Question: Determine the pressure at the turbine exit. In psia
Consider a cylinder of a gasoline engine at the beginning of the compression cycle, duringwhich a fuel/air mixture (for our purposes mostly composed of nitrogen and oxygen, i.e.an ideal gas of diatomic molecules) at 300 K and 1 bar is compressed down to one-tenthvolume (compression ratio of 10:1). Assume that the compression is rapid so no heatexchange occurs with the environment. Calculate the pressure and the temperature ofthe compressed gas. In a diesel engine, the compression ratios are typically much higher;redo the same calculation with a compression ratio of 20:1.
