sixty five pa for every meter. So increase this determine into your chart. As we’re utilizing the equal pressure drop method we can use this tension fall for the many duct lengths so fill Those people in far too. Then we scroll up yet again and align our intersection Along with the upward diagonal traces to view this needs a duct having a diameter of 0.45m so we add that in to the table also.
