MDE 12 Q2

1 / 6

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

D) On the front and back of the heat exchanger

C) On the corners of the heat exchanger

B) On the top and bottom of the heat exchanger

A) On the sides of the heat exchanger

2 / 6

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

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

C) To separate the hot and cold fluids

D) To increase the overall weight of the heat exchanger

B) To provide structural support to the heat exchanger

3 / 6

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

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

A) Plates are arranged in a spiral pattern

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

4 / 6

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

A) The gaskets

C) The flow distribution plates

D) The pressure plates

B) The bolts and frame

5 / 6

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

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

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

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

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

6 / 6

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

D) To insulate the heat exchanger from external temperatures

A) To support the plates mechanically

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

C) To facilitate the flow of fluids between the plates
