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 1.004G0.8 HG = 0.0176G0.37 HG = 1.004G0.37 0.0176G1.37 1.004G0.8 HG = 0.0176G0.37 HG = 1.004G0.37 0.0176G1.37 ANSWER DOWNLOAD EXAMIANS APP
