The type of liquor circulation system to be ' employed in evaporators (viz. natural or forced circulation) is determined mainly by the ______________ of the liquid?
Correct answer: A. Viscosity
- A. Viscosity
- B. Density
- C. Thermal conductivity
- D. Corrosive nature
Explanation
Viscosity strongly affects the ease of liquid circulation: highly viscous liquors offer greater resistance and commonly require forced circulation. Density and thermal conductivity are less decisive for selecting the circulation type.
