The hot water pipe coming out of my boiler is 15mm. Step 1: Determine Required Flow Diameter Use Tables U13 and U14 to determine recommended flow diameter for the required flow rate and type of line. Carter ABSTRACT - Methods for computing peak flood flow through culverts on the basis of a field survey of high- water marks and culvert geometry are presented. 4 feet of head. if these flow rates are exceeded, pipe warranties may be voided. The steeper the grade of the installed pipe, the more water it will carry.
