The Reynolds number is an engineering parameter that relates to the volume flow rate of a fluid through a tube of diameter d as Red = 4Q/nd where v is the fluid kinematic viscosity. Determine the Reynolds number and its uncertainty by general analysis given d=50.4±0.1 mm, Q=0.213± 0.005 m-Ys, v=0.999 x10-6-0.005 x10-6m2/s, which vari- able contributes the most to the overall uncertainty? Assume uncertainties are at 95% confidence.
