1. An oil of density p800 kg/m3 and viscosity u 5 cP flows at 10 liters/min through a 30 m smooth circular pipe of inner diameter 2 cm. It then flows through a filtering section made up of the same pipe packed at void fraction ε-0.4 with solid spherical particles of diameter 0.5 mm to filter out any fine material. All pipe sections are straight as shown. Design constraint: the pressure drop in the packed bed section (call this AP2)...
