🔍 Key Concepts

• Use the psychrometric (relative humidity) chart shown in the illustration • Locate the dry bulb temperature on the bottom axis and move vertically up from 73°F • From the wet bulb temperature of 60°F, move along the correct slanted wet-bulb line until it meets the 73°F vertical

💭 Think About

• What is the wet‑bulb line that passes through 60°F, and where does it intersect the vertical line rising from 73°F dry bulb? • At that intersection point, which curved or labeled line for percent relative humidity does it fall on or closest to? • How far is that intersection from the neighboring humidity curves (e.g., 40%, 50%) — is it closer to one than the other?

✅ Before You Answer

• Be sure you are following the correct family of lines: vertical for dry bulb, diagonal for wet bulb, and gently curved or labeled for % relative humidity • Double‑check that you are reading 73°F, not 72°F or 75°F, on the bottom scale; small mis‑reads change the answer • Confirm that the point you choose lies between 60°F wet bulb and 73°F dry bulb, not on a nearby wet‑bulb temperature line
