DuctSizeCalc vs DuctChecker

This app is an application program to which the size of the duct in air conditioning is an easy to select by the constant-pressure method. It is an easy operation only of the input of the amount of the wind and doing the calculation button the tap. An amount of the wind, disadvantageous pressure, and the velocity of the wind can be calculated by an arbitrary size of the duct. Please use it for the reference when you make the blueprint and the working drawing, etc. It is possible to take an active part by various scenes like the site and meeting, etc. [Feature] - The size of the duct can be easily selected only by inputting an arbitrary amount of the wind and pushing the calculation button. - It corresponds to a circular duct besides the rectangular duct. - Friction loss of default can be changed to arbitrary Friction loss. - The velocity of the wind of default can be changed to an arbitrary velocity of the wind. - If Wight of the size of the duct is changed, it is changed automatically to a proper Height size. (When the WxH interlock switch is turning on.) - Friction loss and the velocity of the wind can be examined by fixing by an arbitrary size of the duct. (When the WxH interlock switch is turning off.) - This application is calculated by metric system. - Please see the support site in detail.

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.
