Question

Q2- Mercury at 26.5 °C is flowing through a packed bed of lead spheres having a diameter of 2.096 mm with a void fraction of 0.499. The supepficial velocity is 0.02198 m/s. The solubility of lead in mercury is 1.721 wt%, the Schuidt number is 124.1, the viscosity of the solution is 1.577 x 10 Pas, and the density is 19530 kg/m'. Load Pb (M.W=207.2) and Mercury Hg (M.W = 200.6) a. Predict the value of Jo. b. Predict the value of k, for the case A diffusing through non diffusing B
