Calculate the pressure exerted by mercury column of 76cm high at its bottom. Given that the density of mercury is 13600kg/m³ and g=9.8 m/s².

P = 101292.8

Explanation:

Use

Pressure p = H D g

H = height ( in metric)

D = density ( in metric )

g = gravity

So

H = 76 cm = 0.76 m

D = 13600 kg/m3

And g = 9.8

P = HDg

= 0.76× 13600×9.8

= 101292.8 pascal

Or = 1.012928 × 10^5
