## Hydraulics & Fluid Mechanics Select the correct statement

Local atmospheric pressure is always below standard atmospheric pressure
Standard atmospheric pressure is the mean local atmospheric pressure a* sea level
Local atmospheric pressure depends upon elevation of locality only
A barometer reads the difference be-tween local and standard atmospheric pressure

## Hydraulics & Fluid Mechanics The discharge of a liquid of kinematic viscosity 4 cm²/sec through a 8 cm dia-meter pipe is 3200n cm7sec. The type of flow expected is

TRANSITION FLOW
LAMINAR FLOW
TURBULENT FLOW
NOT PREDICTABLE FROM THE GIVEN DATA

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

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

2/3 R
1/2 R
1/3 R
3/4 R

## Hydraulics & Fluid Mechanics When a liquid rotates at a constant angular velocity about a vertical axis as a rigid body, the pressure intensity varies

as the square of the radial distance
