sixty five pa for each meter. So add this figure into your chart. As we’re using the equivalent pressure fall approach we can use this strain fall for many of the duct lengths so fill All those in also. Then we scroll up all over again and align our intersection With all the upward check here diagonal strains to see this needs a duct which has a diameter of 0.45m so we include that in the table also.
