How to calculate water tank capacity in gallons

 

Capacity of any water Tank may be found using following basic formula.

Capacity in Gallons = Volume of Tank X 7.4813

1 Cubic Foot volume may contain 7.4813 US Gallons

Rectangular Tank = Volume x 7.4813 US Gallons

                              = Length x Width x Depth x 7.4813

Suppose we have water tank having size of 10 ft x 5ft x 5ft

                               = 10X5X5X7.4813= 1870.32 Gallons

 

   Cylindrical Tank  = Volume x 7.4813 US Gallons

                                 =( πxDxD)/4 x Height x 7.4813

Suppose we have a tank whose diameter is 10 ft and height is 7 ft .

                                  = (3.14 x 10x10) /(4) x7 x7.4813 = 4110.97 US Gallons.

Square Tanks  = Volume x 7.4813 US Gallons

                                 =Length x Width x Height x 7.4813

Suppose we have water tank having size of 10 ft x 10ft x 5ft

                                  = 10x10x5x7.4813 = 3740.65 US Gallons.

Polygon Shape Tank Capacity         =( N.a^2)/4. Cot ϴ x Height x 7.4813

 

Here    N = number of sides

             a = Length of each side

            ϴ = 180 / Number of Sides

            Cot = Cos / Sin

Suppose we have a water tank which has octagonal base having 3 ft length of each side and height is 10 ft.

 

= 8 x (3^2)/4 xCos (180/8) /Sin (180/8) x 10 X 7.4813

= 18X2.4142X10X7.4813=  3251.04 US Gallons
