Problem 17P

The viscosity of clover honey is listed as a function of temperature in Table P10-18. The specific gravity of the honey is about 1.42 and is not a strong function of temperature. The honey is squeezed through a small hole of diameter D = 4.0 mm in the lid of an inverted honey jar. The room and the honey are at T = 20°C. Estimate the maximum speed of the honey through the hole such that the flow can be approximated as creeping flow. (Assume that Re must be less than 0.1 for the creeping flow approximation to be appropriate.) Repeat your calculation if the temperature is 50°C. Discuss.
