Momentum FLux Calculation
 

Hi
I want to calculate the force exerted by a stream of air or water on a plate which is in atmosphere. So for this I could imagine that if I calculate the momentum flux exerted by the stream of air or water on the plate surface which is equal to the force exerted on the surface. So is there any way that we can calculate the momentum flux or equivalent to that in CFD post which we can monitor or measure directly than giving a CEL

Thanks
