I’m seeking advice from everyone: for an oil tank with a height difference of 90m, using natural pressure to push fluid into DN150 pipelines made of stainless steel, with a distance of 2000m to the flow meter, what should be the maximum flow rate at the flow meter?

A method to calculate pipe flow velocity by finding the height difference
It seems that to carry out this calculation, one needs the viscosity and density of the medium at a certain temperature, the pressure behind the flow meter, the internal pressure involved, as well as the resistance of the pipes; one can check the relevant formulas in the book \"Principles of Chemical Engineering\" to see how to perform the calculation.
There are also valves on the pipes, right? There can’t be no valves at all on the pipes
There will be valves, but it is necessary to calculate the maximum value under normal conditions in order to determine the diameter of the flow meter
