Q1. Heat transfer in heat exchanger
Ans. 
Heat transfer in heat exchanger involves the exchange of thermal energy between two fluids without mixing them.
• Heat exchangers are used to transfer heat between two fluids at different temperatures.

• The fluids can flow in parallel or counterflow to maximize heat transfer efficiency.

• Common types of heat exchangers include shell and tube, plate, and finned tube.

• Heat transfer in heat exchangers can be enhanced by using fin

Q2. What is distillation
Ans. 
Distillation is a process used to separate components of a liquid mixture based on their different boiling points.
• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected separately from those with higher boiling points.

• Common examples of distillation include the production of...read more

Q3. What is pump cavitation
Ans. 
Pump cavitation is the formation of vapor bubbles in a liquid due to low pressure at the pump inlet.
• Occurs when the pressure at the pump inlet drops below the vapor pressure of the liquid

• Can lead to damage to the pump components and reduced efficiency

• Symptoms include noise, vibration, and reduced flow rate

• Prevented by ensuring proper suction conditions and maintaining adequate NPSH (Net Positive Suction Head)

Q4. What isheat exanger
Ans. 
A heat exchanger is a device used to transfer heat between two or more fluids, typically to cool or heat a process stream.
• Heat exchangers can be found in various applications such as HVAC systems, refrigeration units, and chemical processing plants.

• They work by transferring heat from one fluid to another through a solid wall without the fluids mixing.

• Common types of heat exchangers include shell and tube, plate, and fi...read more
