sixty five pa per meter. So add this figure in to the chart. As we’re utilizing the equal strain drop strategy we are able to use this pressure fall for all of the duct lengths so fill those in too. Then we scroll up once again and align our intersection with the upward diagonal traces to discover this requires a duct using a diameter of 0.45m so we increase that into the table also.
