QUIZ 1

1. Identify the following fluids:

   

   BLACK is dilatant.
   BLUE is Pseudo plastic ( power law).
   GREEN is Bingham plastic.
   RED is newtonian.

2. Which of the following is a sand-in-water slurry most likely to be ?

   
   Newtonian
   Bingham plastic
   Pseudo plastic
   Dilatant .

3. Would you expect toothpaste to be newtonian ?

   Toothpaste is predominantly a bp, with some characteristics typical of pp's and viscoelastic fluids.

4. Aluminium cannot be classified as a fluid. Would the study of deformations and stress-strain relationships in a bar of aluminium come under rheology ?

   Rheology in general includes studies of deformation in all materials.
