Proper water storage is essential for households, businesses, and industries alike. Whether it’s a rectangular water tank or a round-shaped sump, knowing the capacity ensures efficient use and management. In this guide, we’ll walk you through how to calculate the capacities of both rectangular and round water storage units in simple steps.

Understanding Rectangular Water Tank Capacity

Calculating the capacity of a rectangular water tank is straightforward. Here’s an example:

Example Dimensions

  • Length: 8 feet
  • Width: 6 feet
  • Height: 5 feet

Step-by-Step Calculation

  1. Calculate the Volume
    Multiply the dimensions to get the volume:Volume = Length × Width × HeightSubstituting the values:Volume= 8 × 6 × 5 = 240 ft3
  2. Convert to Liters 
    As 1 cubic foot equals 28.31 liters:Total Volume in Liters = 240 × 28.31 = 6,794.4 

Final Capacity

The rectangular tank can hold approximately 6,794.4 liters of water.

Calculating Sump Capacity for Round Tanks

For a round-shaped sump, the calculation requires slightly different steps.

Example Dimensions

  • Radius: 2 feet
  • Height: 5 feet

Step-by-Step Calculation

1. Calculate the Volume
Use the formula for the volume of a cylinder:

Volume = π × r2 × h

Substituting the values:

 

2. Convert to Liters
Convert the volume to liters using the same conversion factor:

Total Volume in Liters = 62.84 × 28.31 = 1,779 liters

Final Capacity

The round-shaped sump can hold approximately 1,779 liters of water.

Key Insights for Accurate Calculations

  1. Always measure dimensions precisely to ensure accurate results.
  2. All calculations use the standard conversion factor (1 cubic foot = 28.31 liters).
  3. When dealing with irregular shapes, break the shape into simpler geometries and calculate separately.
