Hi! I set them as Autosize. Then I checked the results for "Maximum air flow" for every parallel box: I calculated 50% for every peak and I multiplied it for 0.74, therefore I obtained the power to set. Finally I used a simple proportion ("pressure input"/"power output Autosize simulation"="X"/"power calculated for G3.1.3.14") to obtain the right pressure rise to set for all the fans to get the power previously calculated. Using the equation is absolutely correct but if you don't change the efficiencies it should simply work with a proportion. I also set the fan percent to air flow to 0.
