Hydraulics & Fluid Mechanics According to the principle of buoyancy a body totally or partially immersed in a fluid will be lifted up by a force equal to the weight of the body weight of the fluid displaced by the body less than the weight of the body more than the weight of the body the weight of the body weight of the fluid displaced by the body less than the weight of the body more than the weight of the body ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics In a two dimensional incompressible steady flow around an airfoil, the stream lines are 2 cm apart at a great distance from the airfoil, where the velocity is 30 m/sec. The velocity near the airfoil, where the stream lines are 1.5 cm apart, is 22.5 M/SEC 40 M/SEC 50 M/SEC 33 M/SEC 22.5 M/SEC 40 M/SEC 50 M/SEC 33 M/SEC 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 incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless irrespective of the motion of one fluid layer relative to an adjacent layer ANSWER DOWNLOAD EXAMIANS APP
