A column packed with Mellapak 250Y is operated at 1 atm with air and an aqueous solution at G_x = 8G_y and 60 percent of the flooding velocity (see Fig. 18.8). 

(a) What are the superficial gas velocity and the mass velocity?

(b) If the pressure were changed to 2 atm, what superficial velocity and mass velocity would be used?
