2. Air flows at 400K through a packed bed of cylinders with a diameter of 0.01m and a length equal to the diameter. The vacuum fraction of the bed is 0.30 and the length of the packed bed is 3.50m. The air penetrates transversely into the bed at absolute 2.20atm at a speed of 2.45 kg / m2 * s.
Calculate the air pressure drop in the bed, explaining why it is important to know the pressure drop in it.
