Question

Statement 1: In drying, the vapor pressure of water in the solid is more than outside.

Statement 2: For wet bulb, the greater the velocity, the more rapid is the rate of drying.

(a) True, False

(b) True, True

(c) False, False

(d) False, True

The question was posed to me during a job interview.

The origin of the question is Principles of Food Preservation by Drying-1 topic in portion Principles of Food Preservation by Canning and Drying and Principles of Food Concentrates of Food Engineering

Answer 1

The correct answer is (b) True, True

The best I can explain: In drying, the vapor pressure of water in the solid is more than outside. The difference in the two determines the rate at which water vapor is absorbed by air. For wet bulb, the greater the velocity, the more rapid is the rate of drying.
