Plumbing pipe sizes IN mm and inches

Domestic Water Pipe Sizing Calculation

1 inch= 25.4mm, 1 ft. = 304.8mm, 1 gallon/m=3.785L/m. Water velocity should not be greater than 2.438m/s at valve seat to prevent noise and erosion. So, Pipe area should be at least equal to water flow rate divided by eight.

Storm Drain Pipe Sizing Calculation
