Hydraulics & Fluid Mechanics At the centre line of a pipe flowing under pressure where the velocity gradient is zero, the shear stress will be maximum could be any value minimum negative value maximum could be any value minimum negative value ANSWER DOWNLOAD EXAMIANS APP
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 less than the weight of the body weight of the fluid displaced by the body more than the weight of the body the weight of the body less than the weight of the body weight of the fluid displaced by the body more than the weight of the body ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The shear stress distribution for a fluid flowing in between the parallel plates, both at rest, is zero at the mid plane and varies linearly with distance from mid plane constant over the cross section zero at plates and increases linearly to midpoint parabolic distribution across the section zero at the mid plane and varies linearly with distance from mid plane constant over the cross section zero at plates and increases linearly to midpoint parabolic distribution across the section ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics For a floating body to be in equilibrium All of these meta center should be above e.g. center of buoyancy and e.g. must lie on same vertical plane a righting couple should be formed All of these meta center should be above e.g. center of buoyancy and e.g. must lie on same vertical plane a righting couple should be formed ANSWER DOWNLOAD EXAMIANS APP
