Viscous Liquids - Max. Delivery Flow Velocities

Recommended max. flow velocities on delivery sides of pumps in viscous systems. This tool provides reference velocities for design of piping and pumping systems for viscous liquids across various pipe dimensions.

2	50	1.1	3.6
3	75	1.1	3.7
4	100	1.15	3.8
6	150	1.2	3.9
8	200	1.2	4
10	250	1.3	4.5
