air enters an adaibatic nozzle steadily at 300 kPa, 200 degree celcius and 30m/s and leaves at 100 kPa and 180 m/s.(adsbygoogle = window.adsbygoogle || []).push({});

find the exit temperature?

when m using energy balance equation: h1 + [ (v1)^2 / 2 ] = h2 + [(v2)^2 / 2 ]

i get the answer 184 degree celcius.

but when i use the other relation i.e, pressure temperature relation

[ T1 / T2 ] = [ P1 / p2 ]^ ((k-1)/k) (i used k = 1.4)

i get very different values of temperature. is this equation not valid?

why m i getting different answers?

is this pressure temperature relation only valid for reversible processes?
