Calculate Flow Rate using Pressure & Diameter

Click For Summary
SUMMARY

The discussion focuses on calculating flow rate using pressure and pipe diameter, specifically for a compressed air source at 47 psi and 4 cfm. Participants emphasize the use of the Bernoulli equation and the continuity equation to derive flow rates. The importance of accurate measurements and the relationship between pressure, diameter, and flow rate is highlighted. Tools such as pressure gauges and flow meters are recommended for precise calculations.

PREREQUISITES
  • Understanding of fluid dynamics principles, specifically Bernoulli's equation.
  • Familiarity with the continuity equation in fluid mechanics.
  • Knowledge of pressure measurement using gauges.
  • Basic concepts of flow rate and its units (cfm, psi).
NEXT STEPS
  • Research the Bernoulli equation and its applications in fluid dynamics.
  • Learn how to apply the continuity equation to calculate flow rates in different pipe diameters.
  • Explore the use of flow meters for measuring air flow in compressed air systems.
  • Investigate the impact of pressure changes on flow rates in pneumatic systems.
USEFUL FOR

Engineers, technicians, and anyone involved in designing or maintaining pneumatic systems, particularly those working with compressed air applications.

I need to hook up an instrument that requires a source of compressed air at 47psi and 4cfm. I have a pressure gauge so I can measure the pressure at the source. It seems to me that I should be able to calculate the flow rate if I know the pressure and the diameter of the pipe. Can anyone help me figure that out?
