Semi Filled Horizontal Tank Volume calculator will help in determining the volume of partially filled or fully filled tanks. As you know that horizontal tanks are cylindrical in shape and are commonly used as storage equipment for liquid chemicals, gas or oil. Computing the volume of a horizontal cylinder is easy, but if you want to calculate the volume of liquid in a semi-filled tank, it is quite hard. That is where this online calculator will work.

Types of Horizontal Cylinder
- Flat
- Dished (ASME F&D, or Flanged & Dished)
- 2:1 Elliptical
- Hemispherical
Volume of horizontal cylinder
V_horizontal_cylinder = π * radius² * length = π * (diameter/2)² * length
Partially filled Tanks

When we want to find the volume of the partially filled horizontal cylinder or tanks, we generally know only the liquid height from a level indicator along with the tank dimensions.
