Problem 3. A stream of air passes at a velocity of 45ft/s through a 1.2 Inch cylindrical tuveof internal diameter made of naphthalene. The temperature is 45F and the pressure is 1atm. At this temperature, the vapor pressure of naphthalene is 0.0209mmHg and its diffusivity at air is 0.2ft2/h. a) Determine by correlations at what length of the tube the concentration of naphthalene will be 3.7108lbmol/ft3 b) Determine by the Reynolds analogy at what length of the tube the concentration of the naphthalene will be 3.7108lbmol/ft3 c) Determine by the Chilton-Colburn analogy at whalt length of the tube the concentration of naphthalene will be 3.7103lbmol/ft3 d) Discuss the results obtained
