Automotive Can the Mass Flow Rate of Air Change with Propeller RPM?

AI Thread Summary
The mass flow rate of air through a propeller can indeed change with an increase in the propeller's RPM. A higher RPM results in a greater mass flow rate, assuming a direct connection between the engine and the propeller. Clarification on the setup, such as whether a ducted fan or a different configuration is used, could enhance understanding. Visual aids like sketches or pictures are encouraged for better clarity. Overall, the relationship between propeller speed and air mass flow rate is direct and significant.

Hello everyone,

Can the mass flow rate of air by a propeller connected to an engine through a small tube change if the rpm of the propeller is increased?

I'm afraid your question is very unclear. First I thought a ducted fan. Then a metal tube shaft to the engine. Can you please post a picture or a sketch of what you mean? Use the UPLOAD button at the bottom right of the post edit window to post a picture.
 
If we assume you just have an engine connected to a propeller. Then yes. The faster the engine spins the propeller the greater the mass flow rate.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
