Discussion Overview
The discussion revolves around the feasibility of using a thin pipe to measure total pressure in a flow, specifically in the context of measuring the total pressure of a flame, as an alternative to a pitot tube.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant questions whether any thin piece of pipe could effectively measure total pressure, suggesting that the smoothness of the interior is important.
- Another participant clarifies that typical pitot tubes measure dynamic pressure, which is used to determine fluid speed, and questions if total pressure is indeed what is needed.
- A participant expresses intent to use a thin steel tube for measuring flame speed while avoiding exposure of the pitot tube to the flame.
- There is a general caution about the care needed for instruments when measuring in potentially hazardous environments.
- A link to a product related to pressure measurement is shared, possibly as a suggestion for alternatives.
Areas of Agreement / Disagreement
Participants do not reach a consensus on whether a thin pipe can substitute for a pitot tube in measuring total pressure, and there are differing views on the nature of the measurement required.
Contextual Notes
There are unresolved questions about the accuracy of using a thin pipe versus a pitot tube and the specific requirements for measuring total pressure versus dynamic pressure.
