Explanation

An ideal liquid has the following qualities:
(i) The liquid is perfectly incompressible. It means the density of the liquid remains constant irrespective of pressure.
(ii) The liquid is non viscous, i.e., there are no tangential force between layers of liquid in relative motion.
(iii) An ideal liquid can not withstand any shearing stress, howsoever small the stress may be .
