Sorry, that is not correct. There is a pressure drop around the circuit that
you have to overcome. I published some curves of flow vs pressure a couple
of times to the list, measuring the flow from a Mazda pump flowing through a
mazda block, also delta P across the evaporator cores.

Head pressure in a engine will be near 0

against what head pressure?

rads to the back of the plane, and expect much higher than normal back
pressure. Is there a way to calculate out these sort of numbers?
