Process Equipment and Plant Design Tubes are fixed to the tube sheet (a thick circular metallic plate) by the method of tube rolling and brazing (non-removable) or ferrule connection (removable). Thickness of the tube, sheet is normally __________ the outside diameter of the tube but in no case it should be less than 22 mm (7/8").

Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean 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 HG = 0.0176G0.37 HG = 1.004G0.37 1.004G0.8 0.0176G1.37 HG = 0.0176G0.37 HG = 1.004G0.37 1.004G0.8 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In the case of a shell and tube heat exchanger, the logarithmic mean temperature difference May be either more or less than geometric mean and arithmetic mean value depending upon whether the flow of stream is co-current or counter-current Is always less than arithmetic mean value, but more than geometric mean value Is always more than arithmetic mean value and the geometric mean value Is always less than arithmetic average value May be either more or less than geometric mean and arithmetic mean value depending upon whether the flow of stream is co-current or counter-current Is always less than arithmetic mean value, but more than geometric mean value Is always more than arithmetic mean value and the geometric mean value Is always less than arithmetic average value ANSWER DOWNLOAD EXAMIANS APP
