So assuming that: R1 = R2 = 1 and therefore Rs = R1 + R2 = 2 then: Rp = 1/(1/R1 +1/R2) = 1/2 So: Rp = 1/4 * Rs
Excellent, but what happens in what I suspect might be a more common case of having a parallel setup where the two blocks are NOT equal? How would one figure out the amount of flow that would go through each block?

Example, with totally imaginary numbers...

Branch 1 CPU block, has a resistance of 2ft pressure
Branch 2 GPU block, with a resistance of 4ft pressure

My intuition would say that the system resistance would be around 1.5ft, and that Branch one would get about 2/3 of the total flow, and Branch 2 would get about 1/3. Is this correct? How would I show it by calculation?
