We usually know the Fan flow rate and pressure. How to change it into momentum source. Thanks

-------------------------------------------------------------------- | | INLET | FAN | OUTLET | | -------------------------------------------------------------------- mass flow rate 5kg/s. Fan increase the pressure 100pa. What is the Momentum Source for this case. inlet 0.5m*0.5m. long 5 m, Fan subdomain long 0.3m.

Trial and error? Then getting the mass flow rate is not that hard. Hope the pressure will match....
