Question

What is the relationship between temperature and filtrate volume?

(a) Directly proportional

(b) Indirectly proportional

(c) Equal

(d) Does not depend

The question was posed to me during an online interview.

This interesting question is from Filtration at Constant Volumetric Flow topic in chapter Filtration of Food Processing Unit Operations

Answer 1

Correct option is (a) Directly proportional

For explanation I would say: An increase in temperature increases the filtrate volume. This reduces the viscosity of the filtrate and therefore the filtrate volume also increases.
