The Psychrometric Chart
Additional curves can be added to the chart to represent relative humidity
conditions that are less than 100%. The curves shown are at 10% intervals and
represent humidity conditions ranging from completely saturated air to
completely dry air. When air is completely dry, its relative humidity cannot
change with temperature. The 0% condition is therefore represented by the
horizontal axis of the chart.
This basic chart now shows three air conditions: dry-bulb temperature (vertical
lines), humidity ratio (horizontal lines) and relative humidity (diagonally curved
lines).
