What is a Newtonian fluid?

Back

A Newtonian fluid is a fluid whose viscosity remains constant regardless of the applied shear rate. Its flow behavior is linear, meaning the shear stress is directly proportional to the shear rate.

Front

Which of the following is not a Newtonian fluid?

Back

Dish soap is not a Newtonian fluid; it exhibits non-Newtonian behavior.

Front

What does Pascal's Law state?

Back

Pascal's Law states that an external pressure applied to a fluid in a closed vessel is uniformly transmitted throughout the fluid.

Front

What is the formula for Pascal's Law?

Back

P = F/A, where P is pressure, F is force, and A is area.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is given by Newton's second law: F = ma, where F is force, m is mass, and a is acceleration.

Front

If a car has a mass of 1200 kg and accelerates at 5 m/s², what is the force required?

Back

The force required is 6000 N, calculated using F = ma.

Front

What state of matter has no definite shape or volume?

Back

Gas has no definite shape or volume and can be compressed significantly.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow or deformation.

Front

What is a non-Newtonian fluid?

Back

A non-Newtonian fluid is a fluid whose viscosity changes with the applied shear rate or stress.

Front

Give an example of a Newtonian fluid.

Back

Water is an example of a Newtonian fluid.
