List of top Transport Phenomena and Rate Processes Questions

For an application where the Reynolds number is to be kept constant, a liquid with a density of 1 g cm$^-3$ and viscosity of 0.01 Poise results in a characteristic speed of 1 cm s$^-1$. If this liquid is replaced by another with a density of 1.25 g cm$^-3$ and viscosity of 0.015 Poise, the characteristic velocity will be ......... cm s$^-1$ (rounded off to one decimal place).

Consider a fully developed, steady, one-dimensional, laminar flow of a Newtonian liquid through a pipe. The maximum velocity in the pipe is proportional to which of the following quantities?
Given: $ \Delta P $ is the difference between the outlet and inlet pressure, $ \mu $ is the dynamic viscosity of the liquid, and $ R $ and $ L $ are the radius and length of the pipe, respectively.

At high temperatures, which one of the following empirical expressions correctly describes the variation of dynamic viscosity $\mu$ of a Newtonian liquid with absolute temperature $T$? Given: A and B are positive constants.
