A fluid flows along a flat, horizontal plate which is slightly soluble in the liquid. At a distance, \(x=10 \mathrm{~cm}\) from the leading edge of the plate, the concentration boundary layer thickness, \(\delta_{c}=10 \mathrm{~mm}\), and the local value of the mass transfer coefficient, \(k_{c x}=75 \mathrm{~mol} / \mathrm{m}^{2} \mathrm{~s}\). Determine the numerical values for \(\delta_{c}\) at \(x=25 \mathrm{~cm}\) and for the average mass transfer coefficient, \(\bar{k}_{c}\), over the entire length of the plate \((25 \mathrm{~cm})\). Assume forced convection and laminar flow with \(S c>1\).
