1. Statement 1: hd/k is _____
Statement 2: _____ is the ratio of convective heat transfer to conductive heat transfer.

2. Which of the following is a performance parameter for the food industry?

3. Statement 1: In μ_a= τ/γ = Kγ(n-1) , n = consistency index and K is the flow behaviour index.
Statement 2: n= 1 for Newtonian fluids, n<1 for dilatant fluids and n>1 for pseudo plastic fluids.

4. Statement 1: In Pulsed Electric field, food is kept between two electrodes and electricity is passed to deactivate microbes.
Statement 2: Pulsed Electric field increases shelf life.

5. Which of the following pumps is this pump- It has no rotating or reciprocating parts involved. No leakage. Air/gas used to impart energy.

6. Statement 1: α=k/(ρCp)
Statement 2: α stands for thermal conductivity.

7. XYZ Company wanted to reduce the microbial risk involved with its fresh fruits and vegetables. Hence it introduced Ultra-violet C process which is a photochemical process which reduces the number of microbes (not completely sterilizing them). What else do you think this does?

8. Statement 1: Hurdle technology is a ‘multi-target preservation’.
Statement 2: The main target of food preservation is to help the harmful microorganisms to achieve homeostasis.

9. _____ is the equation for unsteady state heat conduction through solid materials.

10. Rheology of food in the food processing industry is how the food is affected when _____ is applied.
