equation of Continuity

If a liquid enters a pipe of diameter d with a velocity v, what will it’s velocity at the exit if the diameter reduces to 0.5d?

• 2v

• v/2

• v/4

• 4v

The continuity equation is based on

• the principle of conservation of momentum

• conservation of mass

• conservation of energy

• conservation of force

When 0.1 m³/s water flows through a pipe of area 0.25 m² , which later reduces to 0.1 m² what is the velocity of flow in the reduced pipe.

• 2ms^-1

• 0.5 ms^-1

• 0.25 ms^-1

• 1 ms^-1

What will be the velocity of water as it exits the nozzle?

• 8 ms^-1

• 1 ms^-1

• 0.1 ms^-1

• None.

Eqution of continuity is also known as

• frictional flow

• Fluid flow

• flow rate

• None
