Calculation of Liquid Volume in a Horizontal Cylindrical Container This calculator calculates the volume of liquid inside a horizontal cylindrical container at any given height of liquid. Cylinder_volume p R² - r² cylinder_height where R - external radius and r - internal radius To calculate the volume of a cylindrical shell lets take some real-life example maybe. However this can be automatically converted to many other volume units eg.
For simple tanks such a cylinder tank one simply needs to replace the tank height with the observed liquid height in the usual volume of a cylinder equation.
First measure the diameter of the base usually easier than measuring the radius then measure the height of the cylinder. If jostled the container could tip over and pour liquid onto your face or torso. A roll of toilet paper because why not. Where r is the radius of the base circle and h is the height of the cylinder.
