Explain why viscosity is an important property in Fluid Mechanics.

Fluid Mechanics

Part 1:

Static Fluid Systems

Question 1. Compare liquids and gases with regard to their:

 shape
 volume occupied
 density
 viscosity
 compressibility.

Question 2. (a) (i) Define dynamic viscosity and give the mathematical formula for Newton`s law of viscosity.

(ii) How does kinematic viscosity differ from dynamic viscosity?

(b) Explain why viscosity is an important property in Fluid Mechanics.

(c) Name three classes of non-Newtonian fluids and explain how their viscosity is affected by factors other than temperature.

(d) What is the main difference between an ideal` fluid and a real` fluid?
