While working on a simulation, I observed that certain input parameters, such as flow rate and velocity, are not being reflected in the simulation results as expected.

For example if I am giving flow rate as 0.00382kg/sec for 0.61mm diameter of nozzle I am not getting the velocity as 13.11m/s.I was using full solid cone angle.

If you're setting a cone angle that implies a particle injection, but you're displaying fluid velocity vectors. If that's the case, why would the fluid reach the injection speed?

I was trying to validate a paper, they have used same cone angle and they also shown the velocity vectors. But they obtained the velocity correctly if we calculate using continuity equation. So Can you please explain it further how to obtaint the velocity,as I kept same flow rate and diameter to obtain same velocity?
