Turbochargers

This article is part one of a series about turbochargers. In this article, we’ll introduce the equations you need to calculate how much air a turbocharger is flowing. We’ll also see how to calculate the pressure ratio, outlet air temperature, and density ratio. Once we’ve gotten the raw numbers, you’ll learn how to plot them on a compressor flow map and how to read the results.

Don’t worry about getting drowned in math, we’ll take you through it step by step. At the end of the article, we’ll provide an easy to use calculator you can download and use to make all of these calculations yourself without having to step through all of the equations.
