How does a shell and tube heat exchanger typically improve heat transfer efficiency?

• By reducing fluid velocity

• By using multiple tubes to increase surface area

• By using a single large tube

• By decreasing fluid temperature

Why is the spacing between tubes important?

• To minimize the pressure drop

• To ensure proper flow distribution and prevent blockage

• To increase the cost of construction

• To allow for easier cleaning

What is the purpose of the tube bundle in a shell and tube heat exchanger?

What material is commonly used for the construction of the shell to resist corrosion and high temperatures?

• Aluminum

• Copper

• Stainless steel

• Plastic

How can tube arrangement impact heat exchanger performance?

• It can affect the ease of installation

• It can impact the heat transfer efficiency and pressure drop

• It can change the color of the fluid

• It can affect the flow rate only

How does the shell-side fluid usually flow relative to the tube-side fluid?

• In the same direction (parallel flow)

• In a spiral pattern

• In opposite directions (counterflow)

• Randomly

What design feature allows a tube sheet to accommodate thermal expansion of the tube bundle?

• Fixed tube sheet

• Floating tube sheet

• Baffle arrangement

• Expansion joint

In a shell and tube heat exchanger, what is the purpose of the head or channel?

• To seal the ends of the shell and provide access for fluid entry and exit

• To provide additional support for the tube bundle

• To filter the shell-side fluid

• To increase the surface area of the tubes

What design consideration is critical for the channel shell to ensure efficient fluid flow and minimize pressure drop?

• Proper baffle spacing and arrangement

• The color of the channel shell

• The external coating of the shell

• The thickness of the shell material

What type of joint is commonly used to connect the shell to the heads in a heat exchanger?

• Welded joint

• Bolted flange

• Threaded connection

• Clamped joint
