Question

What are modes of heat transfer in evaporators?

(a) Conduction and convention

(b) Conduction and radiation

(c) Radiation and convention

(d) Conduction, convention, radiation

The question was asked in unit test.

I need to ask this question from Heat Transfer in Evaporators topic in chapter Evaporation of Food Processing Unit Operations

Answer 1

The correct answer is (a) Conduction and convention

For explanation I would say: Heat transfer in evaporators is governed by conduction and convention. Calculations on evaporators can be supported by combining mass and energy balances with the principles of heat transfer.
