# A pressure of 2 bar and a velocity of 300… solved problem

#### The gas leaving the turbine of a gas turbine jet engine flows steadily into the engine jet pipe at a temperature of 900°C, a pressure of 2 bar and a velocity of 300 m/s relative to the pipe. Gas leaves the pipe at a temperature of 820°C and a pressure of 1.1 bar. Heat transfer from the gas is negligible. Using the following data calculate the relative velocity of gas leaving the jet pipe. For the gas at t = 820°C; h = 800 kJ/kg and at 910°C, 915 kJ/kg.
