Air enters a turbojet engine at 254 K, 57 kPa and 293 m/s. The pressure ratio across the compressor is 14.5 and the work developed by the turbine equals the compressor work input. If 700 kJ/kg of heat is transferred to air in the combustion chamber, calculate the velocity of air at the exit of the engine, in m/s. Properties of air: Cy=0.718 kJ/(kgK), Cp=1.005 kJ/(kgK), R=0.287 kJ/(kgK), k=1.4

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
