Consider a vertical column packed with glass spheres of diameter 1/16" and with a void fraction of o.60. The column has a diameter of 4" and a length of 10.0 [ft]. Ethanol is

being pumped upwardly through the column. Bourdon manometers monitor the inlet and outlet pressures, which are go [psig] and 40 [psig], respectively. At the operating

temperature, ethanol density and viscosity are 780 [kg/m3] and 1.1 [cP], respectively. In case you need, gc = 32.174 [Ib-ft/lbfs]

. The pressure difference along the column (Po-PL), in (psi), is: The modified pressure difference along the column (Po-P) in (psi), is: The von Krmn number is: The friction factor is: The Reynolds number is: The mass velocity, in [ft/s), is: The superficial velocity, in [ft/s), is: . The mass flow rate, in [1b/s), is: The volumetric flow rate, in (13/8), is The volumetric flow rate, in (sal/min). Ik The flow regime is
