Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the 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 Shell side for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Overall distillation column efficiency for most of the refinery columns can be given by (for μ = 0.07 - 1.4 cp and relative volatility < 4) (where η = overall column efficiency, % μ = molal average viscosity of feed at average column temperature and pressure, cp Δp = pressure drop per tray, psi) Η = 1.66 - 0.25 log μ Η = 17 - 61.1 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) Η = 1.66 - 0.25 log μ Η = 17 - 61.1 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) ANSWER DOWNLOAD EXAMIANS APP
