Models available for pipe sizes 2 through 10. 127 60 each potter vsr series vane type water flow switch 4 wfd40 sku. Friction loss and flow velocities in pvc and cpvc pipes schedule 80 with water are indicated in the table below. Bends w corrugated inner radius.

These values are defined as. Losses are calculated on the basis of flow rates in circular pipes the internal diameter of the pipe the length of the pipe and the type of pipe. Special price 127 60. Change the flow setting on the nozzle to 150 gpm on the same 100 foot line and the friction loss is 35 if you increase the hose length to 200 feet the friction loss becomes 62 psi.

Friction loss t 9 pressure loss in psi per 100 hose equal length siamesed lines. The potter vsr series is the industry standard for flow switches for fire sprinkler systems and is compatible with the widest range of pipe schedules 5 through 40 in the industry as well as all necessary listings and approvals for installation worldwide. Turbine wheel double flow meter. The table may can be used for pipes in other thermoplastic materials where the inner diameter corresponds to pvc pipe schedule 80.

Determine l friction loss in pipe fittings in terms of equivalent length in feet of straight pipe. 1 3 1 6 times value for smooth bend. Special price 127 60.
