$4\mathrm{.}13{?}^{b,d}.$ Pressure drop in beds packed with structured packings

Redesign the packed bed of Problem $4\mathrm{.}12$ using Montz metal B$1-200$ structured packing. Estimate the corresponding mass$-$transfer coefficients. For this packing, $C_{S,T}=3\mathrm{.}116,C_{F,T}=2\mathrm{.}339,a=200m^{-1},=0\mathrm{.}979,C_h=0\mathrm{.}547,C_p=0\mathrm{.}355,C_L=0\mathrm{.}971,$ and $C_V=0\mathrm{.}390($Seader and Henley, $1998$; Billet and Schultes, $1999).$

Answer: $D=0\mathrm{.}961m$;$k_y{a}_h=0\mathrm{.}250$kmo$\frac{l}{m^3}*s$
