WELL YIELD

Well, Yield is defined as the amount of water that can be pumped from a given well per unit of time.

Example: During a test for a well yield, the time required to fill a 100-gallon tank was 0.25 minutes. Based on this pumping rate, what was the well yield in gallons per minute?

Write down the formula.

Well yield, gallons per minute = Volume, gallons

Time, minutes

Make a table of the data

Tank Volume =100 gallons

Time to fill the tank =0.25 minutes

Plug the data into the formula

Well yield, gallons per minute = 100 gallons

0.25 minutes

Divide the number above the line by the number below the line

Well yield, gallons per minute= 400 gallons per minute

Practice Well Yield Calculations

1)During a test for well yield, the time required to fill a 55-gallon drum was 0.35 minutes. Based on this pumping rate, what was the well yield in gallons per minute?

2)During a test for well yield, the time required to fill a 55-gallon drum was 0.15 minutes. Based on this pumping rate, what was the well yield in gallons per minute?

3)Determine the well yield, in gallons per minute if the time required to fill a 200-gallon tank was 0.5 minutes.

4)Calculate the well yield, in gallons per minute if it takes 0.47 minutes to fill a 55 gallon drum.

5)It takes 0.12 minutes for water pumped from a well to fill a 400-gallon drum.What is the well yield in gallons per minute, based on this pumping rate?
