SUMMARY

This discussion focuses on calculating the Cubic Feet per Minute (CFM) flow rate in a tube given its volume and pressure (psi). It establishes that if the pressure drop along the tube, along with the fluid's density and viscosity, is known, one can approximate the flow rate. The conversation also touches on the feasibility of maintaining the same volume and psi while increasing the CFM, indicating that adjustments to the system may be necessary to achieve this. The use of orifice plate equations is referenced as a method for determining flow rates in such scenarios.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of pressure measurement in psi
  • Familiarity with flow rate calculations
  • Basic concepts of density and viscosity of fluids
NEXT STEPS
  • Research the equations for calculating flow rates using pressure drop and fluid properties
  • Explore the use of orifice plates for flow measurement
  • Study the relationship between pressure, volume, and flow rate in fluid systems
  • Investigate methods to increase flow rate while maintaining pressure in a closed system
USEFUL FOR

Engineers, fluid dynamics specialists, and anyone involved in designing or analyzing fluid transport systems will benefit from this discussion.

I don't know if this is the right section, and I am not entirely sure on how to word this- Hoepfully I can make this clear enough however:

If we know the volume of a setup, for a simple example let's just say a small straight tube. If we know the psi inside this tube, is it possible to calculate the CFM going through the tube to get that psi? Is it possible to Keep the same volume tube, retain the same Psi, and increase the cfm?

Hope I've made this clear enough.

If you know the pressure DROP along a tube (or across an opening) and you know the density and viscosity of the fluid you can get the (approximate) flow rate.
It's slightly different equation depending on the speed etc.
