The relative downstream pressure is almost zero , because the lines converge to the reservoir.
This would mean that delta P is the whole pressure I measure right after the pump, which is set by the pressure relief valve. And it would not depend on pipe diameter.
But if I reduce the pipe...
I have an hydraulic circuit where the main flow rate from the pump divides in 2 or more pipes, of different diameters. How can I calculate the exact flow rates in each part?
