Flow calculation

[ris2]

I want to calculate the flow rate from a vertical vessel to a closed tank. I know the pressure in the vertical vessel and the line size to the tank. I know also the pressure in the closed tank. What other information do I need and what calculation can I use? There is a level valve downstream of the vertical vessel which maintains the level in the vessel.

What is the fluid and what is the state in each tank? If it is in a liquid state, what is the level of tank that it is flowing into with respect to the tank it is flowing from? Is the liquid flowing into the top or bottom of the vessel? What is the fluid?

You will also need to know the resistance of any valves in the line
