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 Archimedes’s principle Bernoulli’s equation Continuity equation Pascal’s law Archimedes’s principle Bernoulli’s equation Continuity equation Pascal’s law ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME If Hg is the gross or total head and hf is the head lost due to friction, then net or effective head (H) is given by H = Hg + hf H = Hg/hf H = Hg - hf H = Hg × hf H = Hg + hf H = Hg/hf H = Hg - hf H = Hg × hf ANSWER DOWNLOAD EXAMIANS APP
