🔍 Key Concepts

• Using a psychrometric chart with dry bulb and wet bulb temperatures • Locating the dry bulb temperature (77°F) on the bottom axis, then finding the wet bulb temperature (69°F) line • Following the intersection point to the nearest relative humidity % curve on the chart

💭 Think About

• What is the temperature difference between the dry bulb (77°F) and wet bulb (69°F), and does that suggest relatively high or low humidity? • When you plot 77°F dry bulb and 69°F wet bulb on the chart, which curved % line passes closest to that intersection? • Are the answer choices spaced closely enough that being off by one small grid line would change which % curve is correct?

✅ Before You Answer

• Be sure you are reading dry bulb from the bottom horizontal scale and wet bulb from the slanted scale at the left/top, not mixing them up • Confirm that you are following the intersection point to the correct curved relative humidity line (labeled 50%, 60%, 70%, etc.) • Double‑check that you are not accidentally reading the dew point scale on the right instead of the relative humidity curves in the middle of the chart
