(a). A partial oxidation is carried out by passing air with 1.2 mole percent (mol %) hydrocarbon through 40-mm tubes packed with 2m of 3-mm by 3-mm cylindrical catalyst pellets. The air enters at 350°C and 2.0 atm with a superficial velocity of 1 m/s. What is the pressure drop through the packed tubes? Assume E = 0.40.

(b). How much would the pressure drop be reduced if a 4-mm pellet was used instead? Assume E = 0.40.
