Tube Calculator
Solve for the physical properties of a hollow cylinder or pipe. Ideal for calculating material volume and surface area for construction and engineering.
What is a tube in geometry?
A tube, also known as a hollow cylinder, is a 3D solid bounded by two parallel cylindrical surfaces with the same axis and two parallel circular bases perpendicular to the axis.
How do you calculate the volume of a hollow cylinder?
The volume is the difference between the volume of the outer cylinder and the inner cylinder. Formula: V = π × (R² - r²) × h, where R is the outer radius and r is the inner radius.
What is the surface area of a tube?
The total surface area includes the outer lateral area, inner lateral area, and the area of the two ring-shaped bases (annuli). Formula: SA = 2πRh + 2πrh + 2π(R² - r²).
What is the "Wall Thickness"?
Wall thickness is the distance between the inner and outer surfaces of the tube. It is calculated as (Outer Diameter - Inner Diameter) / 2.
