Which data can NOT be found on a moisture equilibrium chart?

🔍 Key Concepts

• Moisture equilibrium charts are used to relate air temperature, humidity, and cargo moisture for safe carriage of hygroscopic cargoes (like grain or paper). • Think about which properties of air and cargo condition must be compared to know if cargo will gain or lose moisture. • Some of the listed items are air properties (psychrometric), while others are cargo properties.

💭 Think About

• Ask yourself: On a moisture equilibrium chart, what two main things are being brought into balance (in equilibrium) between air and cargo? • Which of the listed options is normally read directly from the chart axes or curves when planning carriage of hygroscopic cargo? • Which choice represents a quantity you would normally calculate or get from tables/met data, rather than read directly from a moisture equilibrium chart?

✅ Before You Answer

• Identify which items are standard psychrometric properties of air (often plotted: dry bulb, wet bulb, relative humidity, vapor pressure). • Identify which item is specifically a property of the cargo, not the surrounding air. • Double‑check which of the four is least likely to appear as a labeled axis or curve on a chart meant to match air condition to cargo condition.
