How do you know how much water is in a well?

Answer 1

This is a multi-step process, but it's pretty simple when broken down into parts. It's pretty much finding the volume of a cylinder. Tie a long string around a rock or use some fishing weights. Lower the weighted end into the well until the weight hits the bottom. Pull the string back up and measure from the weight to where the water (wet spot) stops on the string; this will be called 'h'. You can use any unit of measurement, just be sure to keep it consistent. Now, measure the width of the well, measure from inner wall to inner wall (diameter). Divide the Diameter in half, this is the radius 'r'. So the volume of a cylinder can be found by Pi (times) 'r'-squared (times) 'h' Pi can be simplified to 3.14 Example: 3.14 x 25in. sq. x 56in = 4396cu. in. 231cu. in. = 1gal. 4396cu. in. (divided by) 231cu. in. = 19.03gal.
