Around the chart we begin by drawing a line from 0.sixty five pa/m all of the way up after which draw a line throughout from our demanded quantity move charge, In such cases for part C we need 0.21m3/s. At this intersection we attract a line to locate the velocity and we will see that it falls inside the traces of three and 4m/s so we need to estimate the value, In such a case it get more info seems to be about three.
