Process Equipment and Plant Design In condenser, the cooling water is passed in the tube side in a pass arrangement, because It reduces heat transfer area Pressure drop is reduced It makes condenser compact More thinner tubes can be used It reduces heat transfer area Pressure drop is reduced It makes condenser compact More thinner tubes can be used 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 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 HG = 1.004G0.37 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 HG = 1.004G0.37 ANSWER DOWNLOAD EXAMIANS APP
