Question

3. Flow in a packed bed of particles is described by the Ergun equation: 1300 de+1.75 d 3 Liquid is to be pumped from A to E through a bank of four identical packed contactors arranged as shown in Figure 1. All losses in the large-diameter connecting pipework may be assumed to be negligible. The pressure at the delivery point E, which is 2m above the entry at A, must not fall below 50 kN/m2 gauge. Each contactor is of 0.4m diameter and is packed to a depth of 1m with spherical particles of 1mm diameter. The packing voidage is estimated to be 0.45 (i) For a supply pressure at A of 160 kN/m2 gauge, calculate the flowrate in the connecting line from A to E Data Manufacturing Density of liquid 1020 kg/m3 VitKX3eality of liquid 1.2x10-3 Ns/m2 2 Not to scale Dimensions in metres
