I have only basic math skills. Didn't even take algebra in school (blame it on under-funded rural county school systems in the poorest state in US) for not making me. Anyway, I need help solving a complex math problem. I need the answer in simple layman's terms so I can understand it. Here's my problem....

I have 3/4" PVC water pipe. If the meter is considered starting point with an unknown breaking point, how any feet of water would pass thru the starting point over a 30 day period, 24 hrs per day, 7 days per week, with highest psi being 70# psi.

The water utility company says it is equivalent to the length of 81 tanker trucks lined up end to end with 647,000 gallons of water. What would the psi have to be for that much water to pass thru the starting point?

What say you?
