Calculating Gasflow (CFM) with Pressure (PSI) and Sound (dBuV)

Click For Summary
SUMMARY

Calculating gas flow in cubic feet per minute (CFM) using pressure in pounds per square inch (PSI) and sound levels in decibels relative to a microvolt (dBuV) is not straightforward. The discussion highlights that sound levels are influenced by numerous variables, making it essential to calibrate the calculation for each specific application. The user is developing software to monitor air leaks with the Ultraprobe 9000, which necessitates understanding the relationship between these variables. Without prior knowledge of CFM, establishing a reliable equation is impractical.

PREREQUISITES
  • Understanding of gas flow measurement principles
  • Familiarity with pressure measurement in PSI
  • Knowledge of sound measurement in dBuV
  • Experience with calibration techniques for measurement systems
NEXT STEPS
  • Research calibration methods for gas flow measurements
  • Explore the specifications and capabilities of the Ultraprobe 9000
  • Study the relationship between sound levels and gas flow in various applications
  • Investigate software development techniques for monitoring air leaks
USEFUL FOR

Engineers, software developers, and technicians involved in gas flow measurement, air leak detection, and calibration of acoustic measurement systems will benefit from this discussion.

Hi,

Is it possible to calculate gasflow(cfm) given pressure(psi) and sound(dbuv). I am writing some software to report and track air leaks and the hardware the user will be using is the ultraprobe 9000.

Thanks and I appreciate any information.

Any Ideas??
 
No. Sound depends on so many quantities that it would differ for every application. You would need to essentially calibrate your equation for every separate application you are applying it too, and that would require knowing the CFM to begin with.
