Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - (f - 1)/f (1 - f)/f - 1/f - f/(1 - f) - (f - 1)/f (1 - f)/f - 1/f - f/(1 - f) ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer In case of absorption with exothermic reaction, for fluids having Pr = Sc ; there won Both A & B Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same Pr = Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence Pr = Sc ; there won Both A & B Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same Pr = Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer A pure drug is administered as a sphere and as a cube. The amount of drug is the same in the two tablets. Assuming that the shape and size do not influence the mass transfer, the ratio of rate of dissolution in water at t = 0 for the cubic to spherical tablet is 0.54 1.04 1.94 1.24 0.54 1.04 1.94 1.24 ANSWER DOWNLOAD EXAMIANS APP
