## Hydraulics & Fluid Mechanics The line of action of the buoyant force acts through the centroid of the

volume of the fluid vertically above the body
submerged body
volume of the floating body
displaced volume of the fluid

venturi
orifice plate
pitot tube
rotameter

## 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

less than the weight of the body
more than the weight of the body
weight of the fluid displaced by the body
the weight of the body

## Hydraulics & Fluid Mechanics For a floating body to be in equilibrium

All of these
a righting couple should be formed
meta center should be above e.g.
center of buoyancy and e.g. must lie on same vertical plane

## Hydraulics & Fluid Mechanics Metacentric height is given as the distance between

the center of gravity of the body and the center of buoyancy
the center of gravity of the body andthe meta center
center of buoyancy and metacentre
the center of gravity of the body and the center of pressure

## Hydraulics & Fluid Mechanics The resultant of all normal pressures acts

vertically upwards
at e.g. of body
at center of pressure
at metacentre
