Process Equipment and Plant Design If 'D' is the inside diameter of the shell of a shell and tube heat exchanger, then the baffle spacing is usually in the range of D/5 or minimum 2" to D D/2 or minimum 2" to 5D D/5 or minimum 2" to 5D None of these D/5 or minimum 2" to D D/2 or minimum 2" to 5D D/5 or minimum 2" to 5D 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
