Hydraulics and Fluid Mechanics in ME When a body is immersed wholly or partially in a liquid, it is lifted up by a force equal to the weight of liquid displaced by the body. This statement is called Principle of flotation Bernoulli’s theorem Archimedes’s principle Pascal’s law Principle of flotation Bernoulli’s theorem Archimedes’s principle Pascal’s law ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The Bernoulli's equation is based on the assumption that The velocity of flow is uniform across any cross-section of the pipe No force except gravity acts on the fluid There is no loss of energy of the liquid flowing All of these The velocity of flow is uniform across any cross-section of the pipe No force except gravity acts on the fluid There is no loss of energy of the liquid flowing All of these ANSWER DOWNLOAD EXAMIANS APP
