Hi,
I am working on an adiabatic expansion problem. The problem is that air got compressed and after it is compressed it expands and cools to a certain temperature what causes icing on instruments in the process. I tried to calculate it with the following formula:
p[sub]1[/sub][sup]1-gamma[/sup] * T[sub]1[/sub][sup]gamma[/sup] = p[sub]2[/sub][sup]1-gamma[/sup] * T[sub]2[/sub][sup]gamma[/sup]
p[sub]1[/sub] is 10 bar, T[sub]1[/sub] is 293K, p[sub]2[/sub] is 1 bar, T[sub]2[/sub] must be calculated and gamma is 1.4.
If I fill in the data in the formula, the T[sub]2[/sub] temperature is around -243 C, what is a bit cold and unreal in my eyes.
Anyone who can help me out?
Robert
