Question

Calculate the pressure exerted by liquid column of length 12 CM if the density of the liquid is 2.8 gram per centimetre cube

Answer 1

density=mass/volume=gm/cm3

depth or height =cm

acceleration due to gravity=cm/sec2

pressure= weight density * depth of liquid

= w/v *h

= mg/v *h

=density*g*h.

By substituting above given values ...we can easily determine pressure.
