🔍 Key Concepts

• Using a psychrometric chart to find relative humidity from dry bulb and wet bulb temperatures • How wet bulb depression (dry bulb minus wet bulb) relates to relative humidity • Locating the correct relative humidity curve once you’ve plotted the point

💭 Think About

• On the chart, where do you find the 91°F dry bulb value, and in which direction do the wet bulb temperature lines slope from that point? • After you plot the intersection of 91°F dry bulb and 87°F wet bulb, which labeled relative humidity curve does that point fall on or nearest to? • Is the wet bulb depression (difference between 91°F and 87°F) small or large, and should that correspond to higher or lower relative humidity?

✅ Before You Answer

• Be sure you are reading dry bulb temperature along the bottom horizontal axis • Confirm you are following the correct slanted line for 87°F wet bulb, not a nearby one • Before choosing, double-check which percentage curve label (70%, 80%, 90%, etc.) actually passes through or closest to your plotted point
