11+ Isentropic Flow Equations. Web for an isentropic flow of a perfect gas, several relations can be derived to define the pressure, density and temperature along a streamline. ( % ⋅ ) = 6 h + +.
Involving velocity, pressure, density and temperature as. Our goal is now to see how changes in pressure, density, and velocity relate with changing area. ( % ⋅ ) = 6 h + +.
