To calculate the volume of water in gallons simply multiply the length x width x average depth x 7 5. The water horsepower or minimum power required to run the pump equals where tdh is the total dynamic head in feet q is the flow rate in gpm and sg is the specific gravity 1 for water. Waterfall flow rates for waterfalls and streams your pump should pump at least 100 gallons per hour for every inch wide the waterfall is. A simple calculation to know what the water volume of the fountain or pond is to calculate the length multiplied by the width and times the depth times 7 43 gallons per cubic foot or l x w x d x 7 43 gallons cubic foot.
