🔍 Key Concepts

• Sensible heat gain on a psychrometric chart (what happens to dry‑bulb temperature and which axis that affects) • Humidification vs dehumidification (what happens to grains of moisture / humidity ratio) • How a combined heating + humidifying process appears as a diagonal line between two points on the chart

💭 Think About

• On this chart, if the air is gaining sensible heat, which direction must the process move along the dry‑bulb temperature axis? • If steam is injected, is moisture content increasing or decreasing, and along which axis is that shown? • If both temperature and moisture content are increasing at the same time, where must the outlet point lie relative to the inlet point?

✅ Before You Answer

• Confirm which way dry‑bulb temperature (°F) increases along the bottom axis (left to right or right to left). • Confirm which way grains of moisture per pound of dry air increase along the right‑hand axis (upward or downward). • Combine those two directions to decide where the coil outlet must be located (right/left and above/below) relative to the coil inlet.
