question

One of the two principal methods for the determination of viscosities of gases is thePoiseuille'sflow experiment. In this experiment, a sample of air at 298°K was allowed to flow through a tube with radius 1mm and length 1m. Pressures at both ends of the tube were 765 mm Hg and 760 mm Hg respectively. A volume of 90.2 cm^3 measured at the lower pressure of 760 mm Hg passed through the tube after 100 sec. Calculate the viscosity of air at this temperature.
