Minimum Venturi Diameter??
I'm trying to make a venturi in an application.
I've run some simulations with success, but as soon as I simulate it with the right scale (4mm diameter inlet of pressure) the simulation doesn't appear to show any venturi effect and the vacuum doesn't work.
Does the venturi effect have any minimum diameter to make it possilbe?
If not, how can I generate vacuum using a 4mm inner diameter tube?
