MDE 12 Q2

1 / 6

State THREE advantages of plate-type heat exchangers compared to tube-type heat exchangers.

D) Higher durability, simpler construction, and better temperature control

A) Higher heat transfer efficiency, smaller footprint, and easier maintenance

B) Lower manufacturing cost, higher corrosion resistance, and less space requirement

C) Lower pressure drop, higher fluid velocities, and reduced fouling

2 / 6

Which component in a plate-type heat exchanger helps to maintain the spacing between the plates?

C) The flow distribution plates

D) The pressure plates

A) The gaskets

B) The bolts and frame

3 / 6

What is the primary function of the gaskets or seals in a plate-type heat exchanger?

A) To support the plates mechanically

C) To facilitate the flow of fluids between the plates

B) To ensure the fluids do not mix and to prevent leakage

D) To insulate the heat exchanger from external temperatures

4 / 6

In a plate-type heat exchanger, where are the fluid inlet and outlet connections typically located?

B) On the top and bottom of the heat exchanger

D) On the front and back of the heat exchanger

C) On the corners of the heat exchanger

A) On the sides of the heat exchanger

5 / 6

In a plate-type heat exchanger, how are the plates arranged to facilitate heat transfer?

A) Plates are arranged in a spiral pattern

B) Plates are arranged in a single stack with alternating flow channels

D) Plates are arranged in a stacked circular configuration with a common central inlet

C) Plates are arranged in a parallel pattern with each plate having its own independent channel

6 / 6

What is the purpose of the flow distribution plates in a plate-type heat exchanger?

D) To increase the overall weight of the heat exchanger

A) To direct the fluid evenly across the entire plate surface

C) To separate the hot and cold fluids

B) To provide structural support to the heat exchanger
