Question

Find the pressure on steel due to the liquid mercury at a depth of 76 cm. (Mercury's density 13.6g/cm^3)

Answer 1

h=76cm

Pressure=?

Formula to be used : P=hgd

Where h = height of mercury column and

d= density of mercury=13.6gm/cc

acceleration due to gravity=980cm/s²

P=hgd=13.6×980×76=1012928dyne.cm².

Answer 2

Given: A steel vessel contains the liquid mercury

Density of mercury= 13.6 g/ cm^3

To find: Pressure on steel due to mercury at depth of 76 cm

Explanation: Depth= 76 cm = 0.76 m

Density= 13.6g/cm^3

= 13600 kg/m^3( since 1 g/cm^3 = 1000kg/m^3)

Acceleration due to gravity (g)= 10 m/s^2

The formula for calculating the pressure at some height is given by the formula:

Pressure= Density of mercury* Acceleration due to gravity* height

=> Pressure= 13600*10*0.76 Pa

= 103360 Pa

Therefore, the pressure on steel at a depth of 76 cm is 103360 Pascal.
