Hi there! I'm studying the Flow simulation.

I interpret the axial fan.

I calculate the efficiency.

The first condition

Inlet conditions: mass flow rate [kg / s]

Exit conditions: pressure (positive pressure, voltage, standard atmospheric pressure) [Pa]

The second condition

Inlet conditions: pressure (positive pressure, voltage, standard atmospheric pressure) [Pa]

Exit condition: mass flow rate [Kg / s]

It is what the first condition and the second condition in the condition more accurately?

For the interpretation of the axial flow fan, and how much is the number of grid Mesh?

Research is really important to me.
Thank you in advance.
