Process Equipment and Plant Design The difficulty of liquid distribution in packed towers is accentuated, when the ratio of tower diameter to packing diameter is < 7 > 7 < 15 < 30 > 20 < 50 < 7 > 7 < 15 < 30 > 20 < 50 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 HG = 1.004G0.37 HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 ANSWER DOWNLOAD EXAMIANS APP
