DuctChecker vs Ductulator Duct Sizing使用状況と統計

To determine the size of the duct constant pressure method, static pressure regain method, total pressure method, velocity method. Generally uses constant pressure method. This constant pressure method is how to determine the duct dimensions using the same value per 1 m on all duct friction loss. Usually determined by flow diagrams or duct design for slide rules. You can easily determine the duct by using this program.

Ductulator Duct Sizing

The Duct Sizer App designed based on surveying the needs of engineers. This is a much faster and versatile equivalent of the duct sizing charts provided by top HVAC manufacturers. Get a range of suitable duct sizes by inputting either the maximum friction rate or maximum velocity. Duct sizing for both rectangular and circular ducts. Tap on the values for velocity or friction to switch between calculation methods. Users can change between I-P and S-I units by tapping the toggle switch at the top. The detailed sizing mode allows the Engineer to adjust the duct dimensions and air flow rates, while checking the resulting friction rate and velocity which update automatically. Detailed sizing mode is typically used to analyse existing duct systems. Calculations are based on standard air 0.075 lb/ft3 (1.2 kg/m3) in clean galvanized steel or non-metallic flexible ducts. Any feedback is welcome, and will be the basis for future updates.
