Hydraulics and Fluid Mechanics in ME For a perfect incompressible liquid, flowing in a continuous stream, the total energy of a particle remains the same, while the particle moves from one point to another. This statement is called Bernoulli’s equation Archimedes’s principle Continuity equation Pascal’s law Bernoulli’s equation Archimedes’s principle Continuity equation Pascal’s law ANSWER DOWNLOAD EXAMIANS APP

Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly enlarged to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden enlargement is (v₁² - v₂²)/g (v₁ - v₂)²/g (v₁² - v₂²)/2g (v₁ - v₂)²/2g (v₁² - v₂²)/g (v₁ - v₂)²/g (v₁² - v₂²)/2g (v₁ - v₂)²/2g ANSWER DOWNLOAD EXAMIANS APP
