Thanks for taking your time to help with this. It does sound simple, I am not sure though how to use the pressure value from the fan performance curve. I thought it's the pressure "built up" by the fan downstream? Which means I cannot use it for Bernoulli equation between the slot and the fan...

I understand that the pressure is generated by restricting the airflow, but I think the fan is important as the magnitude of pressure generated has to, somehow, depend on the power of the fan. I am trying to think about an analytical way to model this problem and find a solution that's at least...

I am investigating the feasibility of a powered ground effect device on a road vehicle, as in Brabham BT46

Thanks for your reply Russ, I am trying to use this for calculating force acting on the walls of the inlet duct, resulting from low pressure in the fan inlet and ambient. With the issues you pointed out: 1. I am happy to use V1=/0 2. I am happy to neglect efficiency at the beginning. I will be...

Hi, would anyone be able to advise on this? Let me know if there's anything that's not clear. Thanks

Hi Anorlunda, Apologies, somehow I missed this functionality... all attached "properly" now :)

Hi, This is my first post on the PhysicsFormus I am trying to design an inlet and outlet for an axial fan and calculate velocity and pressure profiles in the duct. See the sketch attached. The ultimate goal is to carry out a CFD study but I was wondering if there is an analytical solution for...
