Use the theory of Prob. 1.50 for a shaft 8 cm long, rotating at 1200 r/min, with ri = 2.00 cm and ro = 2.05 cm. The measured torque is M = 0.293 N•m. What is the fluid viscosity? If the experimental uncertainties are: L (±0.5 mm), M (±0.003 N-m), Ω (±1%), and ri and ro (±0.02 mm), what is the uncertainty in the viscosity determination?
