Calling all plumbers (and others)!
I've posted a few times recently concerning a waterline issue I had. Well, turns out the pipe went bad (full of holes) and needed to be replaced. That was accomplished a few days ago. I had to hire a horizontal driller to run the pipe under the road to the tune of big $$$.
Anyway, I am now trying to calculate the flow rate through this pipe. What I have is a concrete cistern from which I am sucking water to the house with a shallow-well pump. The specs are as follows:
1/2 HP pump putting out a max of 8.5 GPM (6.5 at 40 PSI)
240' of 1" plastic pipe
Water pressure tank - 29.5 gallons with a drawdown of 8.9 gallons
Waterline runs between 4 and 10 feet deep underground
It takes my pump about 4.5 minutes to fill the tank going from 30 PSI to cutting out at 50 PSI. I have heard that a pump should run no more than 1.5 - 2 minutes at a time. I am just trying to calculate flow rate through the pipe and see if my pump is too small for the setup I have. Yes, I know that tees and ells and such create drag and effectively make a longer pipe, but the websites I've visited don't seem to give me a formula for what I want. Any and all help would be appreciated.

I was thirteen, and Kathy (my oldest sister) was seven. At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
