water volumn at pressure
 

I need to know how much water can be expelled from a 1 1/2 in. pipe that is fed from a 5/8 in. valve at 110 psi if said hole is 1/8 in. diameter?

all of it...given enough time

Got a diagram? I can't see the 1/8" opening in there.

How long is the pipe, how much water is in it? Is this a function of how much water volume can be expelled total or how much water volume can be expelled in a given amount of time?

I have a 5/8 in. meter, 1200 ft. of 1 1/2 in. pipe going to a house with 110psi at house.sprung a leak,1/8 in. hole. How much water could come out of that size hole in any given period of time I can figure the rest. I cannot find a chart that shows that kind of pressure.

A lot. And the local authorities really look down on drilling hydrant caps for summer heat relief.

Try defining your question better, and relating it to water cooling.

I assume this is a matter of you not wanting to pay for all the water that leaked out?

That guy only has 15 posts, consider him not a part of these forums :D

By using this online calculator, I'd say you are looking at 95 gpm on average... This could be a fairly large problem..... but this calculator does not take into account the water being pulled through the pipe from other sources- it just measures how much water will move through that orifice at a given pressure. It also doesnt factor the resistance on the other side of the pipe. Heavy clay around the pipe will surely impede flow through the hole. There are really too many factors to compute, but I'd say 95gpm tops.

EDIT: Also, the water going through the hole will be much less when the water in the pipe is flowing fast. When the water is more stagnant, however, you will see a higher flow rate through the hole.

Hope I helped :)

95 GPM? :D Do a little math, calculate what the water velocity would be while going through that 1/8" hole. ;) If the hole was pointed nearly straight up, how high would the water shoot with that velocity? :)
