Question: A modern jet engine has a temperature after combustion of about 1500 K at 3200 kPa as it enters the turbine section, see state 3

A modern jet engine has a temperature after combustion of about 1500 K at 3200 kPa as it enters the turbine section, see state 3 Fig. P.6.107. The compressor inlet is 80 kPa, 260 K state 1 and outlet state 2 is 3300 kPa, 780 K; the turbine outlet state 4 into the nozzle is 400 kPa, 900 K and nozzle exit state 5 at 80 kPa, 640 K. Neglect any heat transfer and neglect kinetic energy except out of the nozzle. Find the compressor and turbine specific work terms and the nozzle exit velocity.
