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"). Half 1.5 times Three fourth Equal to Half 1.5 times Three fourth Equal to ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Ponchon Savarit method is based on the use of enthalpy concentration diagram, which contains the bubble point curve (saturated liquid curve), dew point curve (saturated vapour curve) and equilibrium tie lines. As compared to McCabe-Thiele's method, this method Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method Accounts for the enthalpy changes in the process Is more accurate in finding the number of equilibrium stages All of these Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method Accounts for the enthalpy changes in the process Is more accurate in finding the number of equilibrium stages All of these ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The thickness of segmental baffles (25 -35% cut truncated plates usually) is generally __________ the tube wall thickness. Twice Equal to Four times Half Twice Equal to Four times Half ANSWER DOWNLOAD EXAMIANS APP
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 Are easier to clean Are less prone to fouling None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are easier to clean Are less prone to fouling None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The operating velocity in the absorption tower is usually 40-50% of the flooding velocity. Packed absorption towers are normally designed for a pressure drop of about __________ mm of water column per metre height of packing. 43835 1000-1500 100-150 20-40 43835 1000-1500 100-150 20-40 ANSWER DOWNLOAD EXAMIANS APP
