Q1. What is heat exchangers
Ans. 
Heat exchangers are devices used to transfer heat between two or more fluids, without them mixing together.
• Heat exchangers are commonly used in industrial processes, HVAC systems, and refrigeration systems.

• They work by transferring heat from one fluid to another through a solid wall, without the fluids coming into direct contact.

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

Q2. Explain shell and tube heat exchanger
Ans. 
Shell and tube heat exchanger is a type of heat exchanger that uses multiple tubes enclosed in a shell to transfer heat between two fluids.
• Consists of a shell (outer vessel) and tubes (inner vessels)

• One fluid flows through the tubes while the other flows around the tubes in the shell

• Heat is transferred from one fluid to the other through the tube walls

• Commonly used in industrial processes, HVAC systems, and refrigerati...read more

Q3. Explain npsh in pump
Ans. 
NPSH stands for Net Positive Suction Head and is a measure of the pressure available at the suction port of a pump.
• NPSH is important for ensuring that a pump does not cavitate, which can damage the pump and reduce efficiency.

• It is calculated by subtracting the vapor pressure of the liquid being pumped from the total suction head of the pump.

• NPSH is typically provided by the pump manufacturer and must be greater than th...read more

Q4. What is radiation
Ans. 
Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
• Radiation can be classified into ionizing radiation (e.g. gamma rays, X-rays) and non-ionizing radiation (e.g. visible light, radio waves)

• Ionizing radiation has enough energy to remove tightly bound electrons from atoms, creating ions

• Radiation is used in various fields su...read more

Q5. Formula of friction factor
Ans. 
Friction factor is a dimensionless quantity used in fluid mechanics to describe the amount of friction between a fluid and a surface.
• Friction factor is denoted by the symbol 'f'.

• It is commonly used in the Darcy-Weisbach equation to calculate pressure drop in pipes.

• The formula for friction factor varies depending on the flow regime, such as laminar or turbulent flow.

• For laminar flow, the formula for friction factor is 6...read more
