pressure does not depend on the area or diameter of the tube...
if it would be 50 times wider it would still be da same

dude!!!!
above the liquid is vacuum, its not effected by pressure.
so height will be lower not the same

same level.......b
here is MY EXPLANATION......
barometer is used to measur da pressure...and since IT measures using mercury which is a liquid...
u will use the formula p=h x d x g......agreed.......
now pressure in liquids DOES NOT DEPEND ON AREA OR DIAMETER...
IT depend upon HEIGHT and DENSITY.
so wat ever the diameter the pressure will be the same.....
this is the best explanation i can give...
hope u understood well...
