Question

cooling towers are heat transfer devices used to cool oil.

true
false

Explanation:

Define cooling towers

Cooling towers are specialized heat exchangers designed to reject waste heat into the atmosphere.

Identify the working fluid

These devices primarily use water to transfer process heat and cool it down.

Analyze the statement

The statement claims cooling towers are used to cool oil. While they cool water, which can then be used to cool other fluids like oil via separate heat exchangers, cooling towers themselves do not directly process or cool oil.

Determine the truth value

Since cooling towers directly cool water rather than oil, the statement is technically false.

Answer:

• True
• False (Correct answer)
