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 90.2 cm^3 passed through the tube.
