Discussion Overview

The discussion revolves around the conversion of pressure units, specifically whether 760 mm Hg is equivalent to 1 atm in pascals. It includes aspects of unit conversion and practical applications in fluid dynamics, particularly in the context of a venturi tube.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants question the clarity of the thread title, noting that "mm" is a unit of length and "pascal" is a unit of pressure, suggesting a misunderstanding in the question posed.
  • One participant mentions working on pressure differences in a venturi tube and presents a calculation, expressing uncertainty about the accuracy of their result.
  • Another participant points out that 760 mm Hg is commonly understood to equal 1 atm and suggests that this is also equivalent to 101.325 kPa.
  • Several participants provide links to external resources and previous threads, indicating a preference for continuing discussions in existing threads rather than starting new ones.

Areas of Agreement / Disagreement

There is no consensus on the initial question regarding the conversion of units, as participants express confusion and provide differing perspectives on the topic. The discussion includes both clarification of units and practical applications, but remains unresolved regarding the specific conversion query.

Contextual Notes

Participants express uncertainty about the implications of the calculations presented, and there are references to external resources that may not fully address the original question. The discussion also highlights the potential for misunderstanding in unit conversions.

Search on google, or look up in your conversion table.
EDIT:
Here's a link you ought to have found on your own:

yeh I am havin a little trouble,
im working out the pressure differences in a venturi tube,
A1 = 208
A2 = 210
thus k = 0.99

putting that into the formula 1.4304 x sqrt([2x0.2666x1]/[1-0.99^2])

im getting the answer as 1.43 kg/sec but i don't think this is right?
 
1."mm" is an unit for LEGTH.
2."pascal" is an unit for PRESSURE.
Ergo your thread title makes no sense...

Regarding your problem...What should that answer represent...?

If you already have an active thread in homework help, why are you posting this here? Wouldn't it be better to continue working with the members already helping you?

That was my first reaction, too! Then it occurred to me that he meant "millimeters of mercury".
 
"millimeters of column of mercury"...I guess that should be the long version for TORR (apud Torricelli).

Call me crazy, but doesn't 760 mm Hg = 1 atm = 101.325 kPa?
