9A.2 Computation of the Prandtl numbers for gases at low density. (a) By using the Eucken formula and experimental heat capacity data, estimate the Prandtl number at 1 atm and 300K for each of the gases listed in the table. (b) For the same gases, compute the Prandtl number di- rectly by substituting the following values of the physical properties into the defining formula Pr = Č,µ/k, and com- pare the values with the results obtained in (a). All proper- ties are given at low pressure and 300K.
