Question

“The density of liquids is practically dependent of pressure”?

(a) True

(b) False

I had been asked this question in final exam.

This key question is from Classification of Fluids topic in portion Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

The correct answer is:

(a) True

Explanation: The density of liquids is practically independent of pressure under most conditions. Liquids are relatively incompressible, meaning that even with significant increases in pressure, their density changes very little. This is a key characteristic that distinguishes liquids from gases, whose density can vary greatly with pressure changes.

In bioprocess engineering, this principle is essential for understanding fluid behavior and simplifying calculations for fluid flow.

So, the statement is true: the density of liquids is practically independent of pressure.
