Pipe Pressure

[Roadwork]

I need to know the pressure required to deliver 30 gpm of water, through a 1" copper line. Sounds easy. Can anyone assist?

 

[dcasto]

need to know inlet pressure, outlet pressure and lenght. There are many online calculators for this.

Flow of 60 degree water through 1" copper tubing, assuming no elevation change.

one foot long requires about 0.24 psi
100 foot long requires about 24 psi
1 mile long requires about 1244 psi

The velocity of 12 ft/sec is higher than I would use.

Thanks guys. Are you using/referring to the Bernoulli equation?

The GPM requirement is actually set by US Gov UFC that I am suppose to use for emergency deluge showers.

Most tables are based on Darcy, Colebrook, or perhaps Hazen-Williams equations.

If you are talking about safety showers for wash off chemicals off the body, they typically have 1.25" connections.

Again, if talking about safety showers, you will need to supply tepid water to it.

Hi there:

Check out eFunda at
