1. a) By using the Eucken formula and the associated equation for heat capacity, estimate the Prandtl number at 1 atm and 300 K for Air and H2O. Use the M values given in the table below. b) For the same gases (Air and H2O), compute the Prandtl number directly by substituting the values of the physical properties in the table below into the defining formula Pr = Ĉpμ/k, and compare the values with the results obtained in (a).
