The total packed height = 2.31 + 1.67 = 3.98 m or 13.1 ft. (e) Compute pressure drops for the packed sections from the correlation of Billet and Schultes. The pressure drop per unit height of packed bed is given by Eq. (6-115), 1/ 2 Po - hL P 13300 = exp ( N FrL ) lT lT a 3/ 2 This equation will be used in each section. 1.5 (1) Po a u 2 1 = o 3 o G lT 2 gc KW The required packing parameters are as follows from Table 6.8 and above: FP = 16 ft2/ft3, a = 92.3 m2/m3, = 0.977 m3/m3, Ch = 0.876, and Cp = 0.421 From Eq.
