Here are a few pump math questions:

1. If there is a rectangular pump tank with dimensions of 5 feet wide by 8 feet long, what are the gallons per inch in the tank?

2. What if the pump tank is circular and has a diameter of 5 feet? What are the gallons per inch in this circular tank?

3. If in both tanks the pump height plus the blocks underneath the pump equals 18 inches, how many gallons does it take to cover the pump?

4. If the pump needs to deliver a total of 150 gallons, (assuming there is a check valve) how many inches are between the on and off floats to deliver the dose?

5. What operating depth is needed in each tank to accommodate the necessary gallons to cover the pump and provide the required dose?
