Problem 4: The mean free path of a gas, 2, is defined as the average distance traveled by molecules between collisions. A commonly used formula for estimating 2 of an ideal gas is: where џ is the viscosity of the gas, is the density of air. T is the temperature in Kelvin, and C is an experimentally determined constant. Calculate the mean free path of air (in units of nm) at 25 °C and standard atmospheric pressure if the viscosity...
