Process Equipment and Plant Design Smoker's equation for the calculation of number of equilibrium stages in a continuous binary distillation column is used, when the Number of equilibrium stages required is likely to be very small Number of equilibrium stages in only stripping section is to be calculated Relative volatility is close to one (e.g., separation of close boiling isomers) Feed is not at its bubble point Number of equilibrium stages required is likely to be very small Number of equilibrium stages in only stripping section is to be calculated Relative volatility is close to one (e.g., separation of close boiling isomers) Feed is not at its bubble point ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Heat transfer co-efficient, hG(Kcal/hr.m² .°C) and mass velocity of air, G (kg/hr.m² ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 ANSWER DOWNLOAD EXAMIANS APP
