Pressure loss in pipe
Pressure loss in pipe
(OP)
I typically deal with structural engineering so I don't deal with this type of thing so I figured I would ask on here for help. I was asked if there would be enough pressure at a house.
2" poly pipe
100' elev drop from water main tap to house
1000' water line run
I remember a few things from my thermodynamics class but not enough to determine what pressure there would be at the house.
I am not sure what the pressure is at the main but I can find out if I need to.
Thanks for the help.

You need to determine the head loss for the desired flow rate through the 2" line and see what head remains to generate that flow rate.

Many communities are now require a minimum of 1-Inch services for new construction. The typical residence uses approximately 350 gals per day of water (100 gals per person) with a peak hourly flow of 3-5 gals per minute.
The 100 ft elevation drop will add 62 psi to the incoming water supply.
To confirm, you need to know the required water flow. Put the information into a calculator to come up with the pressure drop.
