Discussion Overview

The discussion revolves around the conversion of force (F) to flow rate (Q) within the context of fluid dynamics. Participants explore the relationships between these quantities and the necessary parameters involved in the conversion process.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant asks how to convert force F into flow rate Q, indicating a lack of understanding of the relationship between these two measures.
  • Another participant asserts that a direct conversion is not possible, suggesting that clarification of the underlying question is needed to provide assistance.
  • A third participant introduces the equation F = rho * Q * v, where rho represents fluid density and v represents fluid velocity, as a starting point for understanding the relationship.
  • A subsequent post seeks to isolate velocity v from the equation, indicating that Q is the desired quantity to determine.
  • Another participant explains that if the cross-sectional area A is known, the volume flow rate can be expressed as Q = vA, leading to a derived equation F = rho * A * v^2, which could help in finding v and subsequently Q.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a direct method for converting F to Q, and multiple approaches and equations are presented without resolution of the underlying question.

Contextual Notes

The discussion highlights dependencies on specific parameters such as fluid density, velocity, and cross-sectional area, which are necessary for any calculations but remain unresolved in terms of specific values or conditions.

Who May Find This Useful

This discussion may be useful for beginners in fluid dynamics or those interested in understanding the relationships between force and flow rate in practical applications.

Hello everyone,

I am newbie here.

Can someone please tell me how can I convert force F into flow rate Q?

Thanks in advance

You can't do a direct conversion like that. They are two completely different units of measure. What are you trying to accomplish? If we know what your question really is we can probably help you.
 
If you are talking about Fluids then force is generally found by

F = rho. Q. v

where rho is the density and v is the velocity of the fluids
 
F = rho. Q. v

The force F and density rho are known, how do I find the velocity v? Q is the quantity I would like to know.
 
If you know the crossed sectional area, A, then the volume flow rate at the crossed section can be defined as:

Q = vA

where v is the velocity,

if you equate these two equations, you will get

F = rho.A.v^2

from this you could probably find v and ultimately, Q.
