Is 760 mm Hg equal to 1 atm in pascals?

In summary, the conversation discusses using Google or a conversion table to find pressure differences in a venturi tube. The formula for calculating this is also provided, with the final answer being in kilograms per second. Additionally, there is a brief discussion on units for length and pressure.

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?

Daniel.
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?
 

What is the formula for converting millimeters to pascals?

The formula for converting millimeters to pascals is: 1 mm = 9.80665 Pa. This means that for every 1 millimeter, there are 9.80665 pascals.

Why do we need to convert millimeters to pascals?

We convert millimeters to pascals to measure pressure. Pascals are a unit of pressure, while millimeters are a unit of length. By converting, we can easily compare pressure measurements with length measurements.

Can you convert other units to pascals, or just millimeters?

Yes, you can convert other units to pascals. Pascals can be converted from other units of pressure, such as atmospheres, bars, or pounds per square inch (psi).

What is the difference between millimeters of mercury and millimeters of water when converting to pascals?

Millimeters of mercury (mmHg) and millimeters of water (mmH2O) are both units of pressure, but they are different in terms of density and fluid type. When converting to pascals, the conversion factor for mmHg is 133.322 and for mmH2O is 9.80665. This means that 1 mmHg is equivalent to 133.322 pascals, while 1 mmH2O is equivalent to 9.80665 pascals.

Is there an easier way to convert millimeters to pascals?

Yes, there are conversion calculators and online tools available that can quickly and accurately convert millimeters to pascals. These tools are especially helpful when dealing with large or complex conversions.
