Question

The normal atmospheric pressure is 76 cm of mercury. Calculate this pressure in S.I. units Whose ever answer I get big I will mark it Brainllest

Answer 1

Answer:

Pressure at that depth =2 atmosphere =2×76cm of Hg

Pressure is due to atmosphere + pressure due to column of

water =2×76cm of Hg

⟹76cm of Hg+ depth × density of

water ×g=2×76cm of Hg

Or

h×d×g=76cm of Hg

Or

h=76cm×13600×

1000

g

×g

Note: pressure due to h meter of Hg=h×densityofmercury×g$$

Cancelling g we have

h=13.6×76=1033.6cm ( as cm is taken for atmosphere answer too comes in cm)
