Ontario Pipeline - Fall 2013 - (Page 32)

WATER BYTES In this new column, water professionals share “bytes” of their knowledge. Consulting engineer Hershel Guttman kick-starts this feature. The Rule of 1.5s. When starting a design for a pumping station or treatment plant, or when checking the design for those facilities, we have often wondered what size of piping to start with, without having to do a full hydraulic analysis. This little rule of thumb was taught to me by Lee Carter, my mentor at Fay Spofford & Thorndike, in Boston, my first consulting job. It goes like this: When sizing piping, except for a header where even distribution of flow is an issue: • Suction piping, maximum velocity of 1.5 m/s. In some cases, with a straight and short suction to a pump, you may increase it to no more than 2.0 m/s. • Discharge piping from a sewage pump, add 1.5 for a maximum velocity of 3.0 m/s. • Discharge piping for water pumps, where grit is not an issue, add another 1.5 for a maximum velocity of 4.5 m/s. • Add a maximum 1.5 m/s to the above two discharge maximum velocities, for the discharge nut of the pump, immediately followed by an increaser.
