G'Day OS!
Isn't cp/cv in dry air a variable with temperature? I know only a teensy bit.
Eg Dry air at 273K cp = 1006 joules/per kg/per K; cv = 719 ditto.
Now I'm moist! cp =? cv = ? cp/cv = ? What happens if I add lots of polyatomic atoms instead of believing air is solely a diatomic gas.
Only splitting hares because I've run out of rabbits but if it's always 1.4 why do I have to look up tables?
Anyway how the devil are you? I shall be in the UK for Farnborough and again for the Gatbash. But not Manchester!
See yuh in the Long Bar!
