🔍 Key Concepts

• Locate the dry bulb temperature of 70°F on the bottom horizontal axis and move vertically up from that point. • From where 70°F lines up, follow the curve for 40% relative humidity until they intersect. • From that intersection, project horizontally to the right-hand grains of moisture scale to read the absolute humidity in grains per pound of dry air.

💭 Think About

• How do the constant relative humidity curves run across this chart, and which one corresponds to 40%? • Once you find the intersection of 70°F dry bulb and 40% relative humidity, which direction must you move to read grains of moisture per pound of dry air? • Compare the value you read on the grains scale with the four answer choices— which one is closest to the point you found on the chart?

✅ Before You Answer

• Be sure you are on the 70°F dry bulb line, not 75°F or 65°F. • Confirm you are following the correct 40% relative humidity curve, not the 30% or 50% curve next to it. • Double-check that you read from the right-hand vertical scale labeled grains of moisture, not the percent relative humidity scale at the top.
