How to Calculate Flow Rates and Volume for Water Wells

Building a new house and need to check the water well yield rate. I go over how to calculate the flow rate of the water getting pumped out of the well as well as how to calculate the amount of static water in the well. Calculate flow rate, calculate the volume of the pipe. How many gallons are there in a foot of 4-inch diameter pipe? Flow Rate.

Informative video. So, what is the estimated flow rate from the well? I think there were a couple of more calculations required? This is obviously a fairly high-volume well. How would this method work if you had your 12 gpm pump in a well that could only produce 1 gpm? If I understood correctly, you are assuming the static water level is where the driller first encountered water. In my experience, these values can be vastly different from the actual static water level. Why don't you just measure the static water level before starting the test? In a low-volume well this could make a huge difference.

Thank you, yes a lot of potential variability.
