Ah Cova thanx for reminding me the electrical analogy (which is perfectly valid until you reach turbulence problems).
Power dissipated through a resistor is P=RI2 (2=square).
R = resistance (fluid analogy = flowresistance)
I = current (fluid analogy = flow rate)
If you put resistors in // you split the current in 2 (knots law)
Draw your own conclusions
Now i dont say its a bad thing, like stated before one must consider the whole circuit. And less flow restriction is a good thing.
Chazz: flow rate is *not* velocity. Its a product of velocity times cross section.
And pressure is *not* flow rate.
Pressure changes greatly through your circuit.
Flow rate (in a closed loop) is THE SAME at ANY point.
(edit) hmm my analogy wasnt very clear. P in fluids will be your heat transfer factor.
