Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dh)/dh (ph - dh)/ph (ph - dh . dt/2)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh)/ph (ph - dh . dt/2)/ph (ph - dt)/ph 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 for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction ANSWER DOWNLOAD EXAMIANS APP
