In shell and tube heat exchanger which fluid should be on the shell side and which inside the tubes?

There are many aspect to consider whether to place any fluid in shell or tube side.
For production: The product stream should be in the tubes side, you can mechanical or chemical clean and inspect the tube side but only chemical treated the jacket side.
When both fluids to exchange are utility stream: It should consider the ease of maintenance well as the energy consumption aspect. Steam heat in vertical shell and tube will have better heat transfer if the steam is in shell and thus smaller size heat exchanger while placing steam on shell would resulted to higher heat loss and more insulation cost.

Disadvantages of shell and tube heat exchanger?
it is difficult to remove the scales. we cannot use scale forming fluid through the shell because if we pass, the scales are formed and it corrodes the shell.
Working principle of shell and tupe heat exchanger?
to cool hot fluit at certain temperature with the help of cold fluid
Advantage of shell and tube heat exchanger over double pipe heat exchanger?
**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time
What is the assumption to design heat exchanger?
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
Who manufactures Fluid TV?

What is Efficiency of shell and tube heat exchanger?
A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.A slightly different definition of efficiency applies to cooling:Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.
