Fluid flow rate, Q (m^3/s), is directly proportional to the average velocity, V (m/s), the area, A (m^2), of the tubing that the fluid is flowing through. Or fluid flow rate is directly proportional to the change in volume, dV (m^3), and inversely proportional to the change in time, dt (s).

Q = Av = dV/dt

Thermal Conductivity, dQ/dt (J/s), is directly proportional to the area, A (m^2), temperature difference, dT (C), and inversely proportional to distance, d (m). The constant, k (J/m*s*C), is different for all materials.

dQ/dt = kAdT/d

So, the longer the material passes through the radiator, larger the change in heat, Q, will be.

So how do we make the time longer while conserving flow rate?

Q = Av, so if you increase the area, the velocity will decrease to keep the same flow.

Hence you divide the pipe, and the pass it through the heatercore / radiators, and the meet them together after their pass through the heatercore / radiator:

Many people have two radiators, but they are only configured in this manner:

With the new setup, you have 1/2v, so time is doubled.... And thus, the cooling of the water by the radiator should be doubled! This is significant because the CPU to Water cooling is hundreds of more times effective then the Water to Air....

If I am missing anything, please advise. If this is good, should I make it a FAQ?
