Hydraulics & Fluid Mechanics Fluid is a substance that cannot remain at rest under action of any shear force always expands until it fills any container has the same shear stress.at a point regardless of its motion cannot be subjected to shear forces cannot remain at rest under action of any shear force always expands until it fills any container has the same shear stress.at a point regardless of its motion cannot be subjected to shear forces ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics For a floating body to be in equilibrium meta center should be above e.g. All of these a righting couple should be formed center of buoyancy and e.g. must lie on same vertical plane meta center should be above e.g. All of these a righting couple should be formed center of buoyancy and e.g. must lie on same vertical plane 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 more than the weight of the body weight of the fluid displaced by the body less than the weight of the body the weight of the body more than the weight of the body weight of the fluid displaced by the body less 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 zero at plates and increases linearly to midpoint parabolic distribution across the section constant over the cross section zero at the mid plane and varies linearly with distance from mid plane zero at plates and increases linearly to midpoint parabolic distribution across the section constant over the cross section ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The horizontal component of force on a curved surface is equal to the force on the horizontal projection of the curved surface product of pressure intensity at its centroid and area weight of liquid vertically above the curved surface force on a vertical projection of the curved surface force on the horizontal projection of the curved surface product of pressure intensity at its centroid and area weight of liquid vertically above the curved surface force on a vertical projection of the curved surface ANSWER DOWNLOAD EXAMIANS APP
