In a shell-and-tube heat exchanger, the flow direction of the fluid through the shell side or tube side can be chosen based on the following principles; which one of these is incorrect? ( ) (A) Materials that are dirty or prone to scaling should flow through tubes that are easy to clean. (B) Materials under high pressure should be used in the tube side. (C) Materials that need to be cooled are generally placed in the shell side to facilitate heat dissipation. (D) Saturated steam is preferably sent through the tube side. 3. Equipment used in industry to facilitate heat exchange between hot and cold ( ) areas is called a heat exchanger. (A) Solid (B) Fluid (C) Powder (D) Gas 4. The arrangement of tubes on the tube sheet in a shell-and-tube heat exchanger can take several forms; which one of them is incorrect?
