The fan terminate the long ducting and at it's blowout has only a very short ducting attached to it.

I understand, have following: Pinlet = -100 Pdischarge = 0 P’inlet = -140 P’discharge = +5

I'm thinking following: Total pressure is constant meaning that the difference in static pressure is one part of the pressure drop that occurs during windy conditions, and this difference in static pressure comes from the two velcoitys, there is no change in static pressure inside the channel...

The fan is inside the duct

Hello Channel are in this case rectangualar ducting, here are some more pictures that maybe better explain what I want to solve.

Hello I'm thinking of how to attack this problem. Outside a channel-inlet, wind is passing perpendicular to the opening with a wind speed of 9 m/s and a fan sucks in a certain amount of air into this channel so that the velocity in the channel is 3 m/s. When the outside air is 0 m/s I have no...
