🔍 Key Concepts

• Using a psychrometric (humidity) chart that relates dry bulb, wet bulb, and relative humidity • Locating the dry bulb temperature on the horizontal axis and the wet bulb temperature line on the chart • Reading the relative humidity percentage curves that run across the chart

💭 Think About

• What happens to the position of the point on the chart when the dry bulb and wet bulb temperatures are very close together—is humidity higher or lower? • Once you mark the intersection of 84°F dry bulb and 81°F wet bulb, which labeled humidity curve (70%, 80%, 90%, etc.) does that point fall on or closest to? • Compare how far your point is from the 100% line versus the 70% line—does it look closer to higher or lower humidity values?

✅ Before You Answer

• Be sure you are reading dry bulb from the bottom horizontal scale (not from the side). • Confirm you are following the correct 81°F wet bulb sloping line, not a neighboring temperature line. • From the intersection point, carefully trace to the nearest labeled relative humidity curve and match it to the closest answer choice.
