Mass Transfer In case of absorption with exothermic reaction, for fluids having 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 Pr = Sc ; there won Both A & B Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer H₂S is being absorbed in a gas absorber unit. The height of the transfer unit based on the overall mass transfer coefficient on the gas side is 0.4 m. The equilibrium data is given by, y = 1.5 x. The bulk concentration of H₂S has to be reduced from 0.05 to 0.001 mole fraction in the gas side. The height of the tower (in metres) corresponding to an operating line given by, y = 5x + 0.001 is 1 0.56 2 1.56 1 0.56 2 1.56 ANSWER DOWNLOAD EXAMIANS APP
