Fluid properties

What is the property of a fluid that resists its flow?

• Density

• Viscosity

• Surface tension

• Pressure

Which property of a fluid is defined as the force per unit area exerted by the fluid?

• Density

• Pressure

• Viscosity

• Flow rate

Which property of a fluid describes its mass per unit volume?

• Flow rate

• Pressure

• Density

• Viscosity

The phenomenon where the liquid surface behaves like a stretched elastic membrane is called:

• Capillary action

• Surface tension

• Viscosity

• Buoyancy

In a viscous fluid flow, the velocity gradient is directly proportional to:

• Shear stress

• Pressure

• Density

• Velocity
