About the chart we start off by drawing a line from 0.65 pa/m all the way up and after that attract a line across from our needed quantity stream rate, In cases like this for part C we need 0.21m3/s. At this intersection we draw a line to locate the velocity and we can easily see that it falls in the lines of three and 4m/s so we have to estimate the value, In this instance it seems to be about three.
The a few branches within the main duct now acquire equivalent air movement earning an important improvement towards the design. This is because a further department now feeds the 3 more compact branches letting a number of the air to smoothly crack far from the leading circulation and feed into these lesser branches.
