Psychrometric Chart Specific Volume -
To read the specific volume on a psychrometric chart:
A coil must cool 5000 CFM of air from 90°F DB, 70°F WB to 55°F DB saturated. Find the mass flow rate.
On a standard psychrometric chart, specific volume lines are running from the upper left to the lower right. They are typically labeled in increments (e.g., 13.0, 13.5, 14.0 ft³/lb dry air). psychrometric chart specific volume
is the inverse of density. It represents the volume occupied by a unit mass of moist air.
Leo stared at the , a chaotic web of lines that looked more like a broken spiderweb than an engineering tool. To most, it was a nightmare of thermodynamics; to Leo, it was the map he needed to save the server room from a meltdown. To read the specific volume on a psychrometric
On a standard psychrometric chart, specific volume lines are often the most overlooked because they look similar to wet-bulb temperature lines, but with a few key differences:
Suppose we want to determine the specific volume of air at 25°C (77°F) and 60% relative humidity. Using a psychrometric chart, we find the point corresponding to these conditions and read the specific volume line that intersects with it. Let's assume the specific volume is approximately 0.86 m³/kg. They are typically labeled in increments (e

The is an essential tool for HVAC engineers and meteorologists, mapping the complex relationship between air, moisture, and energy. Among its various lines and scales, specific volume is a critical parameter used to bridge the gap between a volume of air and its actual mass .
Imagine you have a room with a dry-bulb temperature of and a relative humidity of 50% . Find 75°F on the bottom horizontal axis. Move up until you hit the 50% RH curve. Look for the nearest diagonal specific volume lines .
