From the laws of gaseous flow through orifices under varying differences of pressure, we make out thatin the case of a gauze in motion through the air in a direction perpendicular to its plane, the flow of air through the gauze would at first be nearly proportional to the speed but that subsequently the curve of flow would fall away more and more from the line of proportionality until finally at some very high speed the flow would become constant for any further increase in speed. At the speeds at which motor cars are driven we make out that the falling off from proportionality would only be moderate. EFC. | ||
