Moving perfectly horizontally . You are changing the temperature without adding or removing moisture.

Before you can read the data, you must understand the axes and the lines. The chart is typically plotted with two main axes: how to read a psychrometric chart

Many psychrometric charts feature a protractor-like scale in the upper left corner. This is not for measuring angles, but for plotting or specific processes (like heating or humidification). While advanced, it is helpful to know that this tool exists for drawing process lines between two state points. Moving perfectly horizontally

A psychrometric chart is a graphical tool used to determine the physical and thermal properties of moist air. By identifying just of an air sample, you can locate its unique "state point" on the chart and derive all other environmental characteristics, such as moisture content, energy levels, and volume. Core Components of the Chart The chart is typically plotted with two main

The 100% line is the leftmost boundary of the chart, also known as the Saturation Curve . This indicates the air is "full" and cannot hold more water. D. Wet-Bulb Temperature (WB)
