SUMMARY

This discussion centers on calculating flow rate and pressure for compressible fluids, specifically in the context of fluid mechanics as it relates to automotive applications. The user, Savage147, seeks to understand how to determine the flow rate of a compressible fluid and convert that flow rate into pressure within a known volume. The response emphasizes the necessity of studying fluid mechanics to grasp the complex formulas and principles involved, as a forum cannot encapsulate the depth of knowledge found in textbooks.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Familiarity with incompressible fluid flow concepts
  • Knowledge of compressible fluid dynamics
  • Basic mathematical skills for applying fluid flow equations
NEXT STEPS

I was wondering if somebody could help me out:
Today out of boredom, I was thinking about physics and cars and it sparked a question. I recently learned about incompressible fluid flow and how it is possible to theoretically calculate change in velocity of a fluid flowing through a tube with different cross-sectional areas if the fluids flow rate is constant. I was wondering if there is a way to determine the flow rate of a compressible fluid and also how to convert this flow rate into pressure if it is flowing into an enclosed area of known volume. For instance, a turbine on a engine creates pressure within the intake system by forcing air into the system. So, I want to know which formulae I should use to first - find the compressible from rate and second - convert it into pressure within a container of known volume

Thank you,
Savage147

Yes, all this is possible, but you need to study fluid mechanics. A forum does not provide enough space to lay out all the details like a full fluid mechanics textbook. That's what we have textbooks for.
