## Hydraulics and Fluid Mechanics in ME If the atmospheric pressure on the surface of an oil tank (sp. gr. 0.8) is 0.2 kg/cm”, the pressure at a depth of 50 m below the oil surface will be

2 meters of water column
6 meters of water Column
5 meters of water column
3 meters of water column

## Hydraulics and Fluid Mechanics in ME The flow in a pipe or channel is said to be uniform when

Each liquid particle has a definite path
The quantity of liquid flowing per second is constant
The liquid particles at all sections have the same velocities
The liquid particles at different sections have different velocities

Less than
None of these
More than
Equal to

## Hydraulics and Fluid Mechanics in ME Coefficient of resistance is the ratio of

Area of jet at vena-contracta to the area of orifice
Actual velocity of jet at vena-contracta to the theoretical velocity
Loss of head in the orifice to the head of water available at the exit of the orifice
Actual discharge through an orifice to the theoretical discharge
