A bed is packed with FCC particles of Sauter mean diameter 68,1 um giving a static height of 2.44 m and void fraction of 0.4. A pressure drop reading of 1142 Pa is recorded at a superficial gas velocity of 0.0036 m/s. Calculate the sphericity of the particles at this operating condition. Additional system properties are: ps = 1489.86 kg Pg- 3D1.3- 3. = 0.000018 Pa.s. [10] 3.
