A gas (density = 1.5 kg/m³ , viscosity = 2x 10⁻⁵ kg/m.s) flowing through a packed bed (particle size = 0.5 cm, porosity = 0.5) at a superficial velocity of 2 m/s causes a pressure drop of 8400 Pa/m. The pressure drop for another gas, with density of 1.5kg/m³and viscosity of 3 x 10⁻⁵kg/m.s flowing at 3 m/s will be |
A. | 400 Pa/m |
B. | 2600 Pa/m |
C. | 8900 Pa/m |
D. | 6800 Pa/m |
Answer» C. 8900 Pa/m | |
