Hydraulics & Fluid Mechanics Mercury is often used in barometer because it is the best liquid both (B) and (C) its vapour pressure is so low that it may be neglected the height of barometer will be less it is the best liquid both (B) and (C) its vapour pressure is so low that it may be neglected the height of barometer will be less ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The normal stress is same in all directions at a point in a fluid only when the fluid is frictionless only when the fluid is incompressible and has zero viscosity irrespective of the motion of one fluid layer relative to an adjacent layer When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless only when the fluid is incompressible and has zero viscosity irrespective of the motion of one fluid layer relative to an adjacent layer When there is no motion of one fluid layer relative to an adjacent layer ANSWER DOWNLOAD EXAMIANS APP
