The kinetic theory of gases predicts that the thermal conductivity of a gas equals the product of the heat capacity at constant volume times the viscosity; this theory also predicts that the viscosity varies as the square root of temperature and is independent of pressure. For CO, at 1 atm and 273.15 K, the following dat a are available: Cy = 0.640 kJ kg-' K- %3D u = 1.38 x 10-³ N sm-2 k= 0.01435 Wg'K-' Assuming that c, is proportional to the first power of absolute temperature, estimate k at 300 K and 1 atm. Find the percent error of your estimate based on the literature value of 0.01655 W m-' K¯'.
