Unformatted text preview: Assume that the cross-sectional area of the bed is 1 ft 2 . Use the equation b b p 1- = to calculate p , the particle density, (lb gel/ ft 3 particles) from the density of the silica given in the problem statement 3 b ft lb 39 = and the void fraction 47 . b = . The units of the equilibrium constant, K, should be in gas ft / O H lb gel ft / O H lb 3 2 3 2 to use Equation 15-106 (S&H). If using Excel to solve the Klinkenberg equation, use erf carefully and remember that erf (-z) = - erf (z)....
