Wetted Surface Area Calculator

Accurately determining the wetted surface area of tanks and vessels is crucial in industries like chemical processing, oil and gas, water treatment, and food manufacturing. Knowing the wetted surface area (WSA) helps engineers estimate heat transfer rates, cleaning requirements, and liquid contact areas within containers.

The Wetted Surface Area Calculator is an easy-to-use tool that allows you to calculate:

• Wetted Surface Area (m²)
• Total Surface Area (m²)
• Liquid Volume (m³)

It supports multiple vessel types including vertical cylinders, horizontal cylinders, spheres, cones, and rectangular tanks.

📊 Example Calculation

Let’s say you have a vertical cylindrical tank with:

• Diameter = 2 m
• Height = 5 m
• Liquid Level = 3 m

Steps:

1. Select Vertical Cylinder as the vessel type.
2. Enter values:
   • Diameter = 2
   • Height = 5
   • Liquid Level = 3
3. Click Calculate.

Results:

• Wetted Surface Area = 21.99 m²
• Total Surface Area = 43.98 m²
• Volume = 9.42 m³

This means that 21.99 square meters of the tank’s surface is in contact with the liquid.
