Mechanics of Fluids MCQ App Download & e-Book | 171

Bernoulli's principle states that, for streamline motion of an incompressible non-viscous fluid:

1. the pressure at any part + the kinetic energy per unit volume = constant
2. the kinetic energy per unit volume + the potential energy per unit volume = constant
3. the pressure at any part + the potential energy per unit volume = constant
4. the pressure at any part + the kinetic energy per unit volume + the potential energy per unit volume = constant
