Hi, i'm modeling a flow in a pipe and I've to set the initial velocity at the inlet. But what type of pressure ? 0 in operating pressure and 101325 Pa in gauge pressure or 0 in gauge e 101325 in operating ?
Thanks |

in the operating conditions u just choose the operating pressure.
Gauge pressure is chosen for a specified location |
