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

Click For Summary
SUMMARY

The mass flow rate of air produced by a propeller is directly proportional to the propeller's RPM (revolutions per minute). As the RPM of the propeller increases, the mass flow rate of air also increases, assuming a direct connection between the engine and the propeller. This relationship holds true unless additional constraints, such as ducting or airflow restrictions, are introduced. Clear visual aids, such as sketches or diagrams, can enhance understanding of the setup being discussed.

PREREQUISITES
  • Understanding of fluid dynamics principles

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.
