sixty five pa for every meter. So include this figure in the chart. As we’re using the equal tension drop strategy we could use this pressure drop for each of the duct lengths so fill Individuals in much too. Then we scroll up once more and align our intersection With all the upward diagonal lines to see this demands a duct that has a diameter of 0.45m so we add that into the desk also.
