The following are examples of systematic errors that can occur while using a pipet to transfer a known volume of liquid EXCEPT: The inner surfaces of the pipet are contaminated with soap. The pipet is miscalibrated and holds a slightly different volume of liquid than the indicated volume. The user repetitively reads the volume marking on the pipet from an angle rather than at eye level. The fluctuations in the temperature of the laboratory affected the volume of the pipet and the viscosity of the liquid.

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. What is the viscosity in cp of air at this temperature
