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 im 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 dont 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 occured 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?
