If you ignore specific volume and use standard density, you may undersize or oversize the fan.
Are you looking to use these values for calculations or to determine the mass flow rate for a specific cooling load? psychrometric chart specific volume
To read the specific volume on a psychrometric chart: If you ignore specific volume and use standard
This article explains what specific volume is, how to find it on the chart, and why it matters in real-world applications. The is an essential tool for HVAC engineers
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 .
Note that specific volume is the same as specific heat capacity (which is energy per mass per degree).
