KBD Technic

Jelly Bean

A simple calculator app to perform common airflow calculations required when designing, testing, and balancing industrial ventilation systems.

The user can enter any combination of two for velocity, duct size, or pressure and the calculator will solve for the third (or whichever is selected with the "solve for" checkbox).
This calculator has the ability to correct for changes in air density resulting from non-standard temperatures, elevations, pressures, and humidity. 

Velocity can display/accept the actual velocity, the reading velocity (uncorrected instrument reading for the given density conditions), and velocity pressure. 

Area can display/accept round duct size, square/rectangular duct size, and cross sectional area. 

Volume can display/accept ACFM, SCFM, and lbm of dry air per minute.
