Liquid movement in liquid

[wjkang]

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.

The flow will not stop. It will induce a circulating motion in the vessel. In fact this technique is often used for blending additives into liquids if the densities are not too different.

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.

Do you mean you want to know to what height the tank will be filled? If so, and its a centrifugal pump, convert the pressure remaining at the tank inlet to head, when the pump has backed up on its curve and its flow has reached zero.
