1 / 15

A heat exchanger is a component that:

Cools down substances to the same temperature

Stops the flow of heat altogether

Transfers heat between two substances at different temperatures

Only transfers heat to a hotter substance

2 / 15

Which of the following statements is true about metals?

Metals are usually the best conductors of thermal energy

Metals are poor conductors because of their ionic bonds

Metals do not form a crystalline structure

Metals do not have free-moving electrons

3 / 15

An open cooling water system is characterized by:

Having a surge tank

Not needing any makeup

Being open to the atmosphere

Being sealed off from the atmosphere

4 / 15

Natural convection relies on which driving force?

Buoyancy due to fluid density differences

Pressure

Pumping mechanism

Temperature change

5 / 15

Steam, in its purest form, is:

A solid

A white mist seen above boiling water

A liquid

A completely invisible gas

6 / 15

Which property describes water's ability to stick to itself?

Cohesion

Solvent capability

Conductivity

Adhesion

7 / 15

What is the chemical formula for water?

CO2

H2O

8 / 15

The function of the individual systems that make up the plant is achieved by:

Only moving water

Creating new components

Using basic components in different combinations

Avoiding the use of steam

9 / 15

Why is steam used in a steam engine?

Due to its ability to condense quickly

Because of water's high heat of vaporization

Due to its low heat of vaporization

Because of water's high freezing point

10 / 15

In forced convection:

Heat is transferred only through natural circulation

The fluid remains stationary, allowing heat transfer

The fluid relies on buoyancy due to gravity

A pump, fan, or other means is used to propel the fluid

11 / 15

Convection heat transfer in the plant heat exchangers is a combination of:

Ionic and covalent bonding

Natural circulation and forceful circulation

Transfer of heat in a solid and in a vacuum

Conduction heat transfer and transfer of heat with a fluid in motion

12 / 15

The boiling point of water at sea level is:

212 °F

154 °F

180 °F

39.16 °F

13 / 15

In most heat exchangers, the higher pressure fluid is:

Outside the tubes

On the shell side

Equally distributed

Inside the tubes

14 / 15

Most of the heat exchangers in the plant are:

Counter flow

Turbulent flow

Parallel flow

Crossflow

15 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Moving water from one location to another

Cooling down the core temperature

Controlling radiation levels in the environment
