To find out the pressure drop when a fluid is flowing through a packed bed
1. The sphericity of a spherical particle is
2. Superficial velocity is the?
3. In the packed bed, at relatively low flow rates pressure drop is approximately proportional to gas velocity, true or false?
4. For a packed bed, as the superficial velocity of the fluid increases, the pressure drop:
5. Which of the following factors does not significantly affect pressure drop in a packed bed?
