How do you measure a well diameter?

Well Casing Diameter

1. Take a piece of string or soft (i.e. completely flexible) measuring tape. Wrap around your well casing and measure.
2. If string, put flat, with same degree of tension on it, and measure.
3. Divide your well casing circumference by 3.14.
4. From this number, subtract 5/8″.

How big is a foot of water in a well?

There are 12 inches in a foot so the depth of water in the well is. 12 8 = 96 inches. The volume of a circular cylinder is r 2 h where r is the radius and h is the height. Thus the volume of water in your well is. r 2 h = 15 2 96 = 67858 cubic inches.

How to calculate the volume of water in a well?

Our tool makes it fast and simple to calculate the volume of water (v) and multiply it by 3, thus saving time in the field calculating the purge volumes. Input the well casing inner diameter, the borehole diameter, or the average well diameter over the entire water column, in inches.

How big is a gallon of water pipe?

There are 231 cubic inches in 1 U.S. gallon. Let ServiceTitan’s water pipe volume calculator take the guesswork out of the equation when trying to determine the volume of water in pipes measured in gallons. For common pipe dimensions, contractors can also refer to a general pipe volume chart online.

How do you measure the depth of a well?

When the weight hits the bottom of your well, stop lowering the string and raise it up to then measure the length of the wet part of the rope for an estimated depth of water height. The weighted string is lowered until it hits the bottom of the water well.

The volume of your well can be estimated in gallons using this simple calculation tool below. The equation used is V = πr2h. This calculates pi * radius^2 * the height of the water currently in your well, this gives us the number of cubic inches.

How many gallons of water per foot of depth?

We have about 1.5 gallons of water per foot of depth of a well when we’re using a standard residential 6″ well casing. The height of water column inside the well and available to the pump is less than the total well depth.
