In summary, the individual is seeking help in understanding the concept of fluid flow and how to calculate the change in velocity for a fluid passing through a tube with varying cross-sectional areas. They also inquire about determining the flow rate and converting it into pressure for a compressible fluid in an enclosed area of known volume, specifically in the context of a turbine on an engine. The response advises studying fluid mechanics through textbooks for a more comprehensive understanding of the subject.

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,

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.
 

FAQ: Gas/Fluid Dynamics Help - Calculate Flow Rate & Pressure

What is gas/fluid dynamics and why is it important?

Gas/fluid dynamics is the study of how gases and fluids behave under different conditions, such as pressure and flow rate. It is important because it helps us understand and predict the behavior of gases and fluids in various systems, such as in pipes, pumps, and turbines.

How do you calculate flow rate?

Flow rate is calculated by dividing the volume of fluid that passes through a specific point in a given amount of time. This can be expressed as Q = V/t, where Q is the flow rate, V is the volume, and t is the time.

What factors affect flow rate in gas/fluid dynamics?

There are several factors that can affect flow rate in gas/fluid dynamics. These include the viscosity of the fluid, the diameter of the pipe or channel, the pressure gradient, and the fluid density. Other factors such as temperature and surface roughness may also have an impact.

How is pressure calculated in gas/fluid dynamics?

Pressure is a measure of the force exerted by a gas or fluid on its surroundings. In gas/fluid dynamics, pressure is typically calculated using the equation P = F/A, where P is the pressure, F is the force, and A is the area over which the force is applied.

What are some real-world applications of gas/fluid dynamics?

Gas/fluid dynamics has numerous real-world applications, such as in the design and operation of engines, pumps, and turbines. It is also used in the analysis and optimization of air and water flow in ventilation and plumbing systems. Additionally, gas/fluid dynamics plays a crucial role in the study of weather patterns and ocean currents.
