Calculations in a cylindrical shell (hollow cylinder, pipe, tube). A cylindrical shell is a cylinder, from which in its center a narrower cylinder of the same height is removed. Enter the height and either both radiuses or one radius and the wall thickness. Choose the number of decimal places and click Calculate.
b = R - r
A = 2π * ( R + r ) * ( R - r +h )
L = 2π * h * ( R + r )
V = π * h * ( R² - r² )
π = 3.141592653589793...
Radiuses, height and wall thickness have the same unit (e.g. meter), the area has this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter). The lateral surface is the curved part of the surface area (inner and outer). A/V has this unit -1.
