Static regain method
WebSep 7, 2010 · Static regain is the third sizing method for ductwork included in Design Master HVAC. It is most often used in the high pressure ductwork between the main AHU … WebStatic Regain -Duct design method used on high velocity systems- supply only -based on Bernoulli's equation -sizes the ducts so that the increase in static pressure at each branch offsets the friction loss in the succeeding section of the duct -static pressure should then be the same before each terminal and at each branch

WebJan 10, 2007 · Elite software has a good CD on Static regain, however I am only familier with these four: Static regain method—a method of duct sizing in which duct velocities are systematically reduced, allowing a portion of the velocity pressure to convert to static pressure and offsetting duct friction losses Velocity reduction method—a method of duct WebStatic regain and total pressure methods require the use of computer programs. Velocity reduction is a “rule of thumb” method. Constant velocity is used for short runs of ductwork such as flexible ducts. Flexible ducts are always considered round in shape. Equal Friction Sizing Method. This is the most commonly used method for duct and pipe ...
