MAXIMUM RECOMMENDED FLOW-RATES FOR CLASS

flow rates are based on manufacturer's maximum allowable velocity of 5 feet per second (fps). if these flow rates are exceeded, pipe warranties may be voided. caution should be used so as to avoid the potential for damaging surge pressures. warranties for pipe are void at higher velocities. What is pipe velocity?What is pipe velocity?This is equal to What is pipe velocity? This represents the speed of a fluid in the pipe and what needs to be taken in consideration is that this speed is not uniform across the section area so usually a mean is calculated to offer a continuity result or a steady flow. A practical application of this concept is the water flow in pipes.Pipe Velocity Calculator What is the roughness coefficient of PVC pipe?What is the roughness coefficient of PVC pipe?The results are similar.

$\begingroup$ Are you sure the limit is to prevent the flow becoming turbulent? As for a velocity of 1m/s the pipe would have to have a diameter approx 2mm for it to be laminar. More likely the velocity restriction is due to keeping pressure drop low.
