Mass Transfer The drying time between fixed moisture content within diffusion controlled 'falling rate period' is proportional to (assuming that drying occurs from all surfaces of the solid) (where, T = thickness of the solid ) T³ T T² √T T³ T T² √T 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; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same Pr = Sc ; there won Both A & B 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 = 1; total mass, momentum and thermal diffusivity will be the same ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Component molecules are nonpolar Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution Component molecules are nonpolar Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution ANSWER DOWNLOAD EXAMIANS APP
