Pt = Psup - PLsvc - PLm - PLd - PLe - Psp | (Equation 29-1) |
where:
Pt | = | Pressure used in applying Tables P2904.6.2(4) through P2904.6.2(9). |
Psup | = | Pressure available from the water supply source. |
PLsvc | = | Pressure loss in the water-service pipe. |
PLm | = | Pressure loss in the water meter. |
PLd | = | Pressure loss from devices other than the water meter. |
PLe | = | Pressure loss associated with changes in elevation. |
Psp | = | Maximum pressure required by a sprinkler. |
Step 1—Determine Psup
Obtain the static supply pressure that will be available from the water main from the water purveyor, or for an individual source, the available supply pressure shall be in accordance with Section P2904.5.1.
Step 2—Determine PLsvc
Use Table P2904.6.2(1) to determine the pressure loss in the water service pipe based on the selected size of the water service.
Step 3—Determine PLm
Use Table P2904.6.2(2) to determine the pressure loss from the water meter, based on the selected water meter size.
Step 4—Determine PLd
Determine the pressure loss from devices other than the water meter installed in the piping system supplying sprinklers, such as pressure-reducing valves, backflow preventers, water softeners or water filters. Device pressure losses shall be based on the device manufacturer’s specifications. The flow rate used to determine pressure loss shall be the rate from Section P2904.4.2, except that 5 gpm (0.3 L/s) shall be added where the device is installed in a water-service pipe that supplies more than one dwelling. As alternative to deducting pressure loss for a device, an automatic bypass valve shall be installed to divert flow around the device when a sprinkler activates.
Step 5—Determine PLe
Use Table P2904.6.2(3) to determine the pressure loss associated with changes in elevation. The elevation used in applying the table shall be the difference between the elevation where the water source pressure was measured and the elevation of the highest sprinkler.
Step 6—Determine Psp
Determine the maximum pressure required by any individual sprinkler based on the flow rate from Section P2904.4.1. The required pressure is provided in the sprinkler manufacturer’s published data for the specific sprinkler model based on the selected flow rate.
Step 7—Calculate Pt
Using Equation 29-1, calculate the pressure available to offset friction loss in water-distribution piping between the service valve and the sprinklers.
Step 8—Determine the maximum allowable pipe length
Use Tables P2904.6.2(4) through P2904.6.2(9) to select a material and size for water distribution piping. The piping material and size shall be acceptable if the developed length of pipe between the service valve and the most remote sprinkler does not exceed the maximum allowable length specified by the applicable table. Interpolation of Pt between the tabular values shall be permitted.
The maximum allowable length of piping in Tables P2904.6.2(4) through P2904.6.2(9) incorporates an adjustment for pipe fittings, and no additional consideration of friction losses associated with pipe fittings shall be required.
