Q2. Tube pitch of shell and tube heat exchanger?
Ans. 
Tube pitch is the distance between the center of two adjacent tubes in a shell and tube heat exchanger.
• Tube pitch affects the heat transfer rate and pressure drop in the heat exchanger.

• It is typically between 1.25 and 2 times the outside diameter of the tubes.

• A larger tube pitch can reduce fouling and make cleaning easier, but may require more tubes and increase the size of the heat exchanger.

• The tube pitch should be o...read more

Q2. What is the electrophoresis What is the chromatography
Ans. 
Electrophoresis is a technique used to separate charged molecules based on their size and charge. Chromatography is a technique used to separate components of a mixture based on their affinity to a stationary phase.
• Electrophoresis involves applying an electric field to a gel or solution containing charged molecules, causing them to migrate towards the opposite charge electrode.

• Chromatography involves passing a mixture ...read more
