Question

convert 75cm of Hg into
N/m2, use density of
Hg=13.6g/cm3 and
g=9.8m/s^(2)​

Answer 1

Explanation:

Vertical length of mercury column = h = 75 cm = 0.75 m

Density of mercury = p = 13600 kg m-3

Acceleration due to gravity = g = 9.8 ms-2

Pressure = P = ?

p= hpg

P = 0.75 x 13600×9.8

P = 99960 Pa
