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

centroid of the volume of fluid vertically above the body
centriod of the displaced volume of fluid
center of the volume of floating body
center of gravity of any submerged body

## Hydraulics & Fluid Mechanics The horizontal component of force on a curved surface is equal to the

product of pressure intensity at its centroid and area
force on a vertical projection of the curved surface
weight of liquid vertically above the curved surface
force on the horizontal projection of the curved surface

## Hydraulics & Fluid Mechanics Two pipe systems are said to be equivalent when

head loss and discharge are same in two systems
length and diameter are same in two systems
length of pipe and discharge are same in two systems
friction factor and length are same in two systems

## Hydraulics & Fluid Mechanics The position of center of pressure on a plane surface immersed vertically in a static mass of fluid is

at the centroid of the submerged area
always above the centroid of the area
None of these
always below the centroid of the area
