hello..i have study the flow of the air flow that passing through the car inside the wind tunnel..the problem is how to state the inlet and outlet pressure of the wind tunnel..is the inlet pressure must be 0 kPA or 101.3 kPA and is the outlet pressure must be 0 kPA or 101.3 kPA?..Thanks.

Pressure has a reference value, usually 101.3kPA, so u have to state both pressures to 0

If you want to check the reference value, go to Continua -> Physics 1 -> Reference Values -> Reference Pressure
