# Jet Propulsion/Gas turbine energy exchange

Jump to navigation Jump to search

In a gas turbine processes energy is converted from one form to another.

Changing the velocity of the fluid by pressure changes simultaneously changes the temperature. Compression work raises the apparent temperature of the fluid. We can relate Mach number to the internal energy of the fluid:

${\displaystyle M^{2}={\frac {2}{\gamma -1}}{\frac {u^{2}}{c_{P}T}}}$
