In a psychrometric chart, what does a vertical downward line represent?
Show Hint
A vertical downward line on a psychrometric chart represents the process of dehumidification, where the moisture content of the air is reduced without changing its temperature.

The Correct Option is D
Solution and Explanation
Step 1: Understand the Psychrometric Chart
A psychrometric chart is a graphical representation of the thermodynamic properties of air. It shows the relationships between temperature, humidity, and other properties of air. Step 2: Analyze the vertical downward line A vertical line on a psychrometric chart represents a process where the humidity ratio remains constant. This happens in dehumidification processes where moisture is removed from the air without changing its dry-bulb temperature. Step 3: Conclusion The correct answer is dehumidification process. Final Answer: \[ \boxed{\text{Dehumidification process}} \]
