Liquid movement in liquid
Liquid movement in liquid
(OP)
I want to estimate the distance to which liquid flow can reach.
I have circle tank with 6.6 m diameter and 6 m height.
Through 1.5 inch inlet pipeline, liquid is pumped into this tank as 3 m3/hr flowrate.
At the inlet nozzle, the liquid velocity could estimated as 0.754 m/sec.
How can I calculate the distance from inlet nozzle to flow stop point?
Initial condition of the tank is filled with liquid above the inlet nozzle.

RE: Liquid movement in liquid
If you want to prevent the circulation being set up you need to have 2 or 4 inlets all directly opposite each other - i.e. spaced either 180 or 90 degrees around the circumference. When the jets meet in the middle of the tank they cancel each other. This is often done with the inlet to a decanter where you want as little turbulence as possible in the vessel.
