UTILITIES

Single Point Psychrometrics:
This calculator provides psychrometric properties of air at a glance. It's great for changing humidity units.

Mixed Air Psychrometrics:
This calculator provides instant psychrometric properties of the resulting air of two mixed air streams, e.g. ventilation air mixed with return air.

Duct Calculator:
In a word, it's a classic 'ductulator'. This tool accepts any two choice inputs among CFM (Air Flow Volume), Duct Diameter, Friction Rate (Head Loss), and Air Velocity. This utility will then provide the other two parameters for you. You can enter either a round diameter, or two rectangular dimensions. This tool will optionally display both round and rectangular dimensions, if given a first rectangular dimension, or by inputting a rectangular duct size.


Note:
The above calculators use IP (inch / pound) units.
