Limitations of Bernoulli's equation are:
(i) The Bernoulli's equation is derived by assuming that there is no loss of mechanical energy i.e. sum of pressure energy, potential energy and kinetic energy is constant. But when fluid is in motion, a part of mechanical energy is converted into heat energy.
(ii) The Bernoulli's equation is derived by assuming that liquid is non-viscous. But actually none of the liquids is non-viscous.
(iii)The Bernoulli's equation is derived by assuming that velocity of every fluid particle across any cross-section of pipe is same. But the particles of central layer have maximum velocity and velocity decreases towards the walls of pipe.
