🔍 Key Concepts

• Psychrometric chart layout: dry bulb temperature on the bottom axis and wet bulb temperature lines slanting upward • How wet‑bulb depression (dry bulb – wet bulb) relates to higher or lower relative humidity • Reading and interpolating between the curved relative humidity lines (70%, 80%, 90%, etc.)

💭 Think About

• First, mark the point where 91°F dry bulb aligns with the 87°F wet bulb line. About where on the chart does this point fall relative to the 80% and 90% humidity curves? • Is a small wet‑bulb depression (only 4°F difference) closer to very moist air or fairly dry air? Which answer choices match that expectation? • Compare the 91/87°F point to a nearby pair like 90°F dry bulb and 86°F wet bulb. Which relative humidity curve would that lie on, and how would sliding 1°F to the right change it?

✅ Before You Answer

• Be sure you are using the Fahrenheit scales for both dry bulb (bottom axis) and wet bulb (slanted lines), not the dew‑point scale on the right • Confirm you are following the correct wet‑bulb line (87°F) all the way until it reaches directly above 91°F on the bottom axis • Check which relative humidity curve your intersection lands on or between, and choose the option closest to that percentage
