5.5 Laminar vs Turbulent Flow

Laminar flow means

• Smooth, orderly flow of a fluid

• Static flow with no movement
• Intermittent flow with sudden stops
• Changing flow with varying velocity

• Chaotic flow with unpredictable patterns

Turbulent flow means

• Static and motionless movement of fluid particles
• Predictable and uniform flow of fluid particles
• Chaotic and irregular movement of fluid particles
• Smooth and steady movement of fluid particles
• Regular and organized flow of fluid particles

When a fluid has high viscosity, that means

• The fluid is easy to flow
• The fluid is transparent
• The fluid is resistant to flow and has a thick consistency

• The fluid is cold
• The fluid is odorless

Select all correct options.

Turbulent flow often occurs because kinetic energy is lost to

• sound energy

• thermal energy

• chemical energy

• gravitational potential energy

• water energy

True or false?

Turbulent flow only affects liquids.

• True

• False
