A Poiseuille flow experiment was carried out to measure the viscosity of air at 298 K. The sample was allowed to flow through a 100 cm tube of internal diameter 1 mm. The high pressure end was at 865 Torr and the low-pressure end was at 760 Torr. The volume was measured at the latter pressure. In 59 seconds a volume of 90.2cm passed through the tube. What is the viscosity (use the unit cp) of air at this temperature?
