What are the limitations of Bernoulli's theorem

Posted by Komal Mehta 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 2 months ago

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.

There is no significant difference between oscillations and vibrations. ... Simple harmonic motion is the simplest form of oscillatory motion. This motion takes place when the restoring force acting on the body is directly proportional to its displacement from its equilibrium position.

Priya Dharshini ☺☺ 7 years, 2 months ago

Often the moon turns brown in an eclipse but can become a reddish, coppery colour or orange. Thursday's eclipse sent the moon into a "blood red" colour. The lunar face is usually tinged by light from the Sun that refracts as it passes through our atmosphere. And for different shapeThe apparent different size of Moon is an optical illusion which causes the Moon to appear larger near the horizon than it does higher up in the sky. ... Oddly enough, when our brain focuses on the horizon moon and we perceive it as being farther away it actually makes it appear closer.
