3.33. Air at 1 atm flows at a Reynolds number of 50.000 normal to a long, circular, 1-in.-diameter cylinder made of naphthalene.

Using the physical properties of Example 3.14 for a temperature of

100C, calculate the average sublimation flux in kmol/s-m?

3.34. For the conditions of Exercise 3.33, calculate the initial average rate of sublimation in kmol/s-m? for a spherical particle of

1-in, initial diameter, Compare this result to that for a bed packed with naphthalene spheres with a void fraction of 0.5
