Thru-Hull Fitting Size & Pressure Drop Tool

Flow & System Parameters
GPM (Gallons per Minute)
Target flow for cooling/system usage.
Select a standard pipe size. (ID is Inner Diameter)
Feet (ft)
The complexity affects the fitting loss (K factor).

Calculation Summary
Total Pressure Drop ($\Delta P_{total}$)

-- PSI

-- bar / -- ft
Flow Velocity (V)

-- ft/s

Max safe velocity is generally 6-8 ft/s.
