Air and Nytrogen

[AO1958]

Hello

hope all is fine

Please, I have to realize a calculation for a Nitrogen cooler.
Nonetheless I have available the sole properties of air.

My question is: my I realize an approximation and consider nitrogen as dry air (that is , relative humidity = 0)?

Many thanks
