- fluid efflux speed and how quickly a container is emptied
Hello Forum,
The speed of efflux ##v_{efflux}## of a liquid, say water, from an orifice in the lower part of a container depends on the vertical distance between the free surface of the fluid and the lower position of the orifice in the container itself. The faster the speed ##v_{efflux}## the quicker the container will be emptied.
Assuming the same vertical separation between free surface and orifice position, how do the orifice diameter ##D## and the shape of the orifice impact the speed at which the container is emptied?
I believe that both the orifice diameter ##D## and shape should/could have an effect on how quickly the container gets emptied. Different orifice shapes would probably produce different ##v_{efflux}## for the same orifice diameter ##D##. In theory, the diameter ##D## should not matter since the continuity equation stating that ##D_1 v_1 = D_2 v_2## but I wonder if in real life a larger diameter ##D## would empty the container faster...
Thanks!
