Hot gases enter a jet engine turbine with a velocity of 50 m/s, a temperature of 1200 K, and a pressure of 600 kPa. The gases exit the turbine at a pressure of 250 kPa and a velocity of 75 m/s. Assume isentropic steady flow and that the hot gases behave as a perfect gas with constant specific heats (mean molecular mass = 25; y = output in kJ/(kg of mass flowing through the turbine). 1.37).

Question

Kindly answer the extra question related to the main question. Thanks!

If you wanted to increase your turbine power output you could do that by
burning more fuel to raise your inlet temperature or you could add heat
through the outer casing of your turbine. What about the outlet velocity?
Should the outlet velocity be higher or lower when you want to obtain
more turbine power output?
