Hello!

I need your help with this...
Through a nozzle with diameter 5 mm, there is an air flow. The mass flow is 0.01 kg/s, and the flow is horizontal. The air flows into air with atmospheric pressure. How far will the air flow reach before the velocity is zero? Or even better, is it possible to calculate how the velocity varies with the distance from the nozzle?

Seemed so easy, but can't figure it out...
