Equivalent Diameter

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...

Archimedean spiral

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 ,...

Roll length calculator

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...
