Hydraulics and Fluid Mechanics in ME When the flow parameters at any given instant remain same at every point, then flow is said to be laminar quasi static uniform steady state laminar quasi static uniform steady state ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME A moving fluid mass may be brought to a static equilibrium position, by applying an imaginary inertia force of the same magnitude as that of the accelerating force but in the opposite direction. This statement is called Archimedes’s principle D-Alembert’s principle None of these Pascal’s law Archimedes’s principle D-Alembert’s principle None of these Pascal’s law ANSWER DOWNLOAD EXAMIANS APP
