How to develop a cone or how to create a flat pattern of a cone can be achieved in a few easy geometrical steps The geometrical method shown below does however have inaccuracy, so at the end of this hub I have included a mathematical formula to help produce an accurate conical development...

The equivalent diameter is the diameter of a circular duct or pipe that for equal flow gives the same pressure loss or resistance as an equivalent rectangular duct or pipe A round shape results in lower pressure drops and less fan horsepower to move the air and, consequently, smaller equipment...

The Archimedean spiral (also known as the arithmetic spiral) is a spiral named after the 3rd-century BC Greek mathematician Archimed It is the locus of points corresponding to the locations over time of a point moving away from a fixed point with a constant speed along a ,...

Derivation of the exact formula To calculate the exact length of the spiral, we write the equation of the curve in polar coordinates: Here ρ is the distance between the axis as a function of the angle φ φ is expressed in radians and is 0 at the beginning and increases by 2π every turn So, every turn the radius ρ increases by h...
