should I use real gas or ideal gas for the following simulation? Air flows in, it's an open system, and one wall is heated.

1) If I am to use a real model for the air, which model should I use? Redlich-Kwong ?

2) Where do I enter the outlet pressure at gauge pressure in the outlet area?

3) I have defined the following speed for named expressions: (Re*DynamicViscosity)/(Density*d)

does the calculator for DynamicViscosity and Density take the correct values at the input temperature of 298 K?


I hope you can help me.

Many Thanks
