Hey guys! I'm brand new to the forum and looking for some advice. For full disclosure, I am actually an Economics major, but I absolutely love learning about mechanical engineering; more specifically automotive mechanical engineering. Haha. I have been looking all over the web for about a month now but have yet to find an answer to my question, which is this: How do I calculate the amount of force a car engine's exhaust produces after leaving the cylinders? The eventual idea is to capture the force by way of a turbine. I think of it kind of like a watermill and a stream. I am talking about right as it leaves the cylinders (think of where the turbine of a turbocharger would be). I realize the amount of Force would depend on things like rpm's, air density, psi, engine displacement, volume of the turbine, etc. resulting in a range of values. So how would y'all figure it out? Any and all help is GREATLY appreciated!
