Hydraulics & Fluid Mechanics The normal stress is same in all directions at a point in a fluid 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 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 ANSWER DOWNLOAD EXAMIANS APP
