I don't see the difference. It's a closed circuit.
There is a pressure drop across the engine, and one across the radiator, both
drops determined by the flow and their individual resistance to that
flow. It's the A+B=B+A thing (isn't it?)
There will be a
difference in pressure along the circuit, though it may not be enough to really
matter to us. You mentioned electrical circuits before. Imagine a
simple series circuit, with a 10V battery (pump), and two 5 ohm
resistors (engine and radiator). The highest voltage (pressure) will exist
at the terminal of the battery (outlet of the pump). Every time it goes
though a resistor it will drop.
I just noticed your web
site name :-) That's funny.
