At this intersection we draw a line to discover the velocity and we are able to see that it falls in the lines of 3 and 4m/s so we need to estimate the worth, In this instance it appears to be about three.
325 kPa. We will glimpse this up in our air Qualities tables but I like to just use a web based calculator as its more rapidly. So we just fall These numbers in and we obtain the density of air remaining 1.two kg/m3.
