Properly Size a Cooling Water Manifold
Before you order a manifold, do the math.
The total flow rate of all ports combined should be less than or equal to the flow rate of the supply or return.

According to our handy reference chart, a reasonable rate of flow for a 3/4" inlet is 15 Gallons per Minute. On a 16-port manifold, that leaves you with less than one gallon per minute available to each circuit if the flow through the ports is balanced. Supply as much flow as possible. You can always slow things down with a valve or regulator.

For the best possible cooling conditions, ensure Turbulent Flow. Remember about our on-line tool for Turbulent Flow Calculations.
