Process Equipment and Plant Design Triangular pitch tube layout as compared to square pitch in a shell and tube heat exchanger Permits the use of more tubes in a given shell diameter Permits the use of less tubes in a given shell diameter Both B and C Facilitates comparatively easier external cleaning because of large clearance Permits the use of more tubes in a given shell diameter Permits the use of less tubes in a given shell diameter Both B and C Facilitates comparatively easier external cleaning because of large clearance ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the clearance of the tube is generally More than the tube diameter Equal to the tube diameter More in case of triangular pitch as compared to the square pitch tube layout Not less than one-fourth of the tube diameter or 3/16" More than the tube diameter Equal to the tube diameter More in case of triangular pitch as compared to the square pitch tube layout Not less than one-fourth of the tube diameter or 3/16" ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The optimum size ratio for two mixed reactors in series depends on the kinetics of the reaction and the conversion level. For reaction orders more than one, the Equal sized reactors are the best Larger reactor should come first Smaller reactor should come first None of these Equal sized reactors are the best Larger reactor should come first Smaller reactor should come first None of these ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction ANSWER DOWNLOAD EXAMIANS APP
