Now that you have had the chance to look over How to Calculate Time to Pump Out a Tank, try these practice problems:
- If two 300 gpm pumps are used, how long will it take in hours to empty a rectangular tank 100 feet long by 45 feet wide and 27 feet deep? The pumps are 88 percent efficient.
- A 92,000 gallon tank receives 410,000 gpd flow. A 276 gpm pump is attached to the tank, but it is broken. How long do they have to repair or replace the pump before the tank will overflow? Assume the tank is empty now.
- The wet well at a lift station receives a flow of 345 gpm. The wet well has a diameter of 27 feet. How many minutes will it take to raise the water level 7 feet in the wet well?
