SUMMARY

760 mm Hg is equivalent to 1 atm, which is also equal to 101.325 kPa. This conversion is crucial for understanding pressure measurements in various scientific contexts, particularly in fluid dynamics and gas laws. The discussion highlights the importance of distinguishing between units of length and pressure, clarifying that mm Hg refers to millimeters of mercury, a standard unit for measuring pressure. Participants also emphasize the relevance of using accurate terminology when discussing physical concepts.

PREREQUISITES
  • Understanding of pressure units, specifically mm Hg and atm
  • Familiarity with the ideal gas law and fluid dynamics
  • Basic knowledge of the Venturi effect and its applications
  • Ability to perform unit conversions in physics
NEXT STEPS
  • Research the relationship between pressure and fluid dynamics in Venturi tubes
  • Learn about the ideal gas law and its implications for pressure measurements
  • Explore the concept of pressure conversion between different units, such as mm Hg, atm, and kPa
  • Investigate the historical context and significance of Torricelli's work on pressure measurement
USEFUL FOR

This discussion is beneficial for physics students, engineers, and anyone involved in fields requiring precise pressure measurements and conversions, particularly in fluid mechanics and thermodynamics.

how do i do this?
thanks

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?
