Advantages: Simplicity of design; Easy to clean and maintain; ideal for fluids that cause fouling. Disadvantages: Length cannot be extended beyond a limit Rate of heat transfer is low + high cost when considering amt of heat transfer. Heat looses occur from the outer shell.
electrons revolve around the nucleus . shell is the path of the electron whre the electrons revolves. subshell is the region around the nucleus where you can find the probability of electron most. so shell attains circular/elliptical shape where as subshell attains different shapes(spherical,dumb-bell...etc)

One can mix shell Dial Oil B and nytro 10xn at 2 parts shell Diala and one part nytro 10xn. The advantages would be good pouring flow even at low temperature Both oils are napthenic.
Royal Dutch Shell is for 2009, followed by Exxon Mobil and then BP
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned

Crabs keep better in the the shell.

Hi.. For only filmwise condensation, horizontal position gives higher condensation coefficent than verical position. In case of condensation with subcooling in a shell and tube heat exchanger, condensation coefficient is higher with horizontal postion while subcooling coefficient is higher with vertical position. kal....
It means that it found a better one. Which means it has grown and needs a bigger shell.
It's you choice if you like soft get that, if you play outside a lot with your 3DS I suggest you get the shell:)
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.
They are both good.
The Java Expert System is better and very similar to the CLIPS.
Square pitch is used in HEX and condensers when a fluid that is prone to fouling is flowing through the shell side. Square pitch allows for easier cleaning but the heat transfer isn't as high as triangular pitch because less tubes can be placed. If you don't have a fluid that is prone to fouling (adding layers of junk to the tubes) you can use triangular which allows you to place more tubes in the HEX so higher heat transfer.
A window already has a casing around it to protect and allow condenser venting. An air conditioner that is made for a sleeve has no protective shell around it, so if you put a window air conditioner in a sleeve you will not get good air circulation from the fan that cools off the condenser. That will result in high pressure at the compressor, high temperature at the condenser and high temperature at the evaporator. This will result in poor cooling and probable compressor failure which will allow you to go out and buy an air conditioner that is designed for a sleeve.
