Flow riser
WebFlow velocities are dependent of the friction factor that is dependent on the construction data of each air lift and therefore no general relation can be derived. The riser velocity values found are in the range of 0.1 up to more than 1 m s −1 for pilot plant (10 l) up to commercial scale (> 1000 m 3) reactors [14]. WebFeatures. Ball valve with lockable handle. Fewer joints minimise risk of leaks. Factory fitted pressure gauge. Dual ports enable the flow switch to be mounted on either side. Full bore test valve.
