Mass Transfer The change in enthalpy per unit weight of adsorbed gas when adsorbed on gas free or "outgassed" adsorbent to from a definite concentration of adsorbate is called its Integral heat of adsorption Heat of wetting Heat of normal condensation Differential heat of adsorption Integral heat of adsorption Heat of wetting Heat of normal condensation Differential heat of adsorption ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer An aqueous solution of methanol is to be distilled in a tray column. High pressure steam is available as a source of heat. For a given reflux ratio and overhead composition, two options are being explored; (i) a reboiler is used and (ii) no reboiler is used but steam is fed directly to the bottom of the column. As compared to option (i), in option (ii) More number of trays are required and the residue composition is more dilute in methanol Composition of the residue remains unchanged Less number of trays are required More number of trays are required but the residue composition remains unchanged More number of trays are required and the residue composition is more dilute in methanol Composition of the residue remains unchanged Less number of trays are required More number of trays are required but the residue composition remains unchanged 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.
