Pressure drop online calculator for small mobiles.
1 water meter pressure loss.
This version is usable for browsers without javascript also.
If you modify the initial design flow later you should come back and change the water meter flow sensor psi loss values as well.
Example water flow through a hose and pressure loss.
This will be true of all your psi losses in the pressure loss table that are based on flow.
Includes 53 different calculations.
Toilet flow 2 5 gpm shower flow 2 5 gpm total flow 5 gpm.
Service line head loss based on the proposed service line size c.
Fittings head losses from all fittings and valves to the customer side of the meter domestic water meter and service run table lot no.
The equation presupposes a fluid that has a.
Constant from table multiplied by 0 4335 pressure loss in psi.
2 gpm 7 6 liter min flows through a 1 2 garden hose with length 82 feet 25 m.
The pressure drop in the hose can be calculated as 5 psi 100 ft 80 ft 100 ft 4 psi 0 28 bar.
In this equation h l represents friction head loss meters of h2o l represents length of pipe meters d represents internal pipe diameter meters q represents flow rate through the pipe cubic meters per second and c represents the hazen williams coefficient which will vary according to how smooth the internal surfaces of the pipe are.
We are using 1 2 inch pipe.
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.
