Can I Measure Total Pressure with a Thin Pipe Instead of a Pitot Tube?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using a thin steel pipe to measure total pressure instead of a traditional pitot tube. Participants confirm that while a pitot tube is designed to measure dynamic pressure, a smooth, thin pipe can be utilized to capture total pressure, particularly in applications involving flames. The accuracy of measurements is emphasized, with caution advised regarding instrument exposure to high temperatures. The user ultimately decides to proceed with a thin steel tube for measuring flame speed while ensuring the integrity of their instruments.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with pressure measurement techniques
  • Knowledge of pitot tube functionality and applications
  • Experience with high-temperature measurement environments
NEXT STEPS
  • Research the design and calibration of thin pipe pressure measurement systems
  • Explore the principles of dynamic versus total pressure measurement
  • Learn about flame speed measurement techniques and their instrumentation
  • Investigate the properties and applications of high-temperature resistant materials
USEFUL FOR

Engineers, researchers, and technicians involved in fluid dynamics, combustion analysis, and pressure measurement who seek alternative methods for measuring total pressure in high-temperature environments.

Since pitot tubes measure total pressure from the flow ramming into the total pressure hole, could I use any thin piece of pipe facing the flow (given that it's smooth on the inside) to measure total pressure? Trying to think of ways not to use my pitot tube to measure the total pressure of a flame. Thanks!
 
Engineering news on Phys.org
Normaly there is no flow in a pitot tube, so the smooth schould be in the opening of the tube.
It's just a question of accurasy in the messure.

Is it really the total pressure you want ?
A typical pitot tube are used to result in the dynamik pressure whitch gives you speed / flow of the fluid messured.
 
Thanks for the reply. So OK, I'll use a thin steel tube then. And yes, I'm trying to find the flame speed and have a static port set up, but I don't want to expose my pitot tube to the flame.
 
That's right, take care of the instruments.
