High pressure fluid in a shell and tube heat exchanger should preferably be routed through the

Shell side for smaller total pressure drop

Tubes to avoid the expansion of high pressure shell construction

Shell side for large overall heat transfer co-efficient

Shell side, if the flow is counter-current and tube side if the flow is co-current

Shell side for smaller total pressure drop

Tubes to avoid the expansion of high pressure shell construction

In case of design of a shell and tube heat exchanger,

All of these

Minimum tube sheet thickness (in which tubes are fixed) is equal to the O.D. of the tube upto 15 mm tube diameter; and for > 15 mm tube diameter, tube sheet thickness is smaller than tube diameter

O.D. of the tube is 6 to 40 mm while the tube lengths used are 0.5, 2.5, 3.0, 4.0, 5.0, 6 metres

Minimum cleaning lane of 6.5 mm is provided, when tubes are on a square pitch
