Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir length for a bubble cap plate is the same as that for the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns 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 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 HG = 1.004G0.37 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 ANSWER DOWNLOAD EXAMIANS APP
