1 Water Meter Pressure Loss

Toilet flow 2 5 gpm shower flow 2 5 gpm total flow 5 gpm.

1 water meter pressure loss. This will be true of all your psi losses in the pressure loss table that are based on flow. If you modify the initial design flow later you should come back and change the water meter flow sensor psi loss values as well. Enter the psi loss from the table below on the water meter line of the pressure loss table. 2 gpm 7 6 liter min flows through a 1 2 garden hose with length 82 feet 25 m.

12 5 2007 11 17 43 am. Constant from table multiplied by 0 4335 pressure loss in psi. Find your meter size below then use your initial design flow from your design data form to find the psi loss. Pressure loss through water meters.

Let s calculate what will happen to the pressure if we flush a toilet while a shower is running in a bathroom 100 feet away from where the water enters the house. Equations displayed for easy reference. We are using 1 2 inch pipe. From the diagram above the pressure loss per 100 feet can be estimated to 5 psi.

The pressure drop in the hose can be calculated as 5 psi 100 ft 80 ft 100 ft 4 psi 0 28 bar. If you don t have a water meter just enter 0 on the table. Online calculator to quickly determine pressure loss through piping for water.
