A Tank Weight Calculator helps estimate the weight and capacity of liquid stored inside cylindrical tanks. This calculator is commonly used in construction, industrial storage, chemical processing, agriculture, fuel storage, and water tank applications.

By entering the tank diameter, tank height, liquid density, and fill percentage, you can quickly calculate tank volume, liquid weight, and total storage capacity.

Tank Volume Formula

The tank volume is calculated using the cylinder volume formula.

Volume=π×(Diameter2)2×Height\text{Volume}=\pi\times\left(\frac{\text{Diameter}}{2}\right)^2\times\text{Height}Volume=π×(2Diameter​)2×Height

Where:

  • Diameter = Tank diameter
  • Height = Tank height

Filled Volume Formula

If the tank is partially filled:

Filled Volume=Volume×Fill Percentage100\text{Filled Volume}=\text{Volume}\times\frac{\text{Fill Percentage}}{100}Filled Volume=Volume×100Fill Percentage​

Liquid Weight Formula

The liquid weight is calculated using filled volume and liquid density.

Weight=Filled Volume×Density\text{Weight}=\text{Filled Volume}\times\text{Density}Weight=Filled Volume×Density

Total Weight Formula

If multiple tanks are used:

Total Weight=Weight×Number of Tanks\text{Total Weight}=\text{Weight}\times\text{Number of Tanks}Total Weight=Weight×Number of Tanks

How the Tank Weight Calculator Works

The calculator first computes the total cylindrical tank volume. Then it adjusts the volume using the fill percentage and multiplies the result by liquid density to estimate the liquid weight.

This calculation is commonly used for:

  • water tanks
  • fuel storage tanks
  • chemical tanks
  • oil storage systems
  • industrial liquid containers

Example Calculation

Suppose:

  • Tank Diameter = 2 m
  • Tank Height = 3 m
  • Liquid Density = 1000 kg/m³
  • Fill Percentage = 80%
  • Number of Tanks = 2

Step 1: Calculate Tank Volume

Volume=π×(22)2×3\text{Volume}=\pi\times\left(\frac{2}{2}\right)^2\times3Volume=π×(22​)2×3

Volume Result

Volume≈9.425 m3\text{Volume}\approx9.425\ \text{m}^3Volume≈9.425 m3

Step 2: Calculate Filled Volume

Filled Volume=9.425×80100\text{Filled Volume}=9.425\times\frac{80}{100}Filled Volume=9.425×10080​

Filled Volume Result

Filled Volume=7.54 m3\text{Filled Volume}=7.54\ \text{m}^3Filled Volume=7.54 m3

Step 3: Calculate Liquid Weight

Weight=7.54×1000\text{Weight}=7.54\times1000Weight=7.54×1000

Weight Result

Weight=7540 kg\text{Weight}=7540\ \text{kg}Weight=7540 kg

Step 4: Calculate Total Weight

Total Weight=7540×2\text{Total Weight}=7540\times2Total Weight=7540×2

Final Total Weight

Total Weight=15080 kg\text{Total Weight}=15080\ \text{kg}Total Weight=15080 kg
