Question 1.
What is the definition of density?
Show hintHide hint
Think of what density means in everyday terms.
Question 2.
How does specific gravity relate to water?
Show hintHide hint
Consider how heavier or lighter substances compare to water.
3Question 3.
What is the relationship between shear stress and velocity gradient according to Newton's law?
- They are inversely proportional
- They are directly proportional
- They are independent
Show hintHide hint
Think about how shear stress changes with flow speed.
4Question 4.

- True
- False
Show hintHide hint
Consider the definition of specific gravity.
Question 5.
You have two fluid samples. Liquid A has a density of 1200 kg/m³, and Liquid B has a density of 800 kg/m³. Calculate the specific gravity of both liquids.
Show hintHide hint
Remember to compare each density with the density of water.
Question 6.
Design an experiment to illustrate how viscosity changes with temperature. What observations would you make?
Show hintHide hint
Consider practical examples like oil or syrup.
