Expert Answer:

There are following limitations of Bernoulli's theorem:

(i) In Bernoulli's theorem, the velocity of every particle of liquid across any cross-section is considered uniform which is not correct. The velocity of the particles is different in different layers.
(ii) The loss of energy when the liquid is in motion is not considered while some kinetic energy is converted into heat and is lost.
(iii) The fluids must be incompressible as the elastic energy of the fluid is not taken into account.
