The Oval Swimming Pool Water Capacity and Time to Fill calculator determines the capacity of a oval (rounded ends) swimming pool based on the length and the width of the pool and the desired depth of water and the approximate time to fill the pool with a garden hose.
INSTRUCTIONS: Enter the following:
- (L) Length of Oval Pool
- (W) Width of Oval Pool
- (wD) Depth of Water in Pool
- (FR) Hose Flow Rate
Volume Capacity (V): The volume of water is returned in gallons (gal) and liters (l). The calculator also returns the time to fill the pool in hours.
The Math / Science
This calculator determines the amount of water at a constant depth of a round ended or oval swimming pool, multiplying the volume in cubic feet times 7.5 gallons (gal.) because there are 7.5 gallons of water in 1 cubic foot. If you are calculating the capacity of a circular hot tub with seats around the edges simply run this equation twice, once using the measurements from the bottom to the top of the seats and again from the top of the seats to the fill line of the hot tub.
The formula for the capacity of an oval shaped pool is:
V=(π⋅(W2)2+W⋅(L-W))⋅wDV=(π⋅(W2)2+W⋅(L−W))⋅wD
where:
- V = Water volume (capacity) of the pool
- L = Length of the pool
- W = Width of the pool
- wD = Depth of the pool
The time to fill the pool is based on the range of flow rate for garden hoses of between 9 gallons per minute to 17 gallons per minute. A default of 12 gallons per minute is provided. This should be used as an estimate.
