1 / 15

Natural convection relies on which driving force?

Pumping mechanism

Buoyancy due to fluid density differences

Temperature change

Pressure

2 / 15

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

Natural circulation and forceful circulation

Ionic and covalent bonding

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

Transfer of heat in a solid and in a vacuum

3 / 15

The boiling point of water at sea level is:

212 °F

39.16 °F

180 °F

154 °F

4 / 15

Most of the heat exchangers in the plant are:

Parallel flow

Crossflow

Counter flow

Turbulent flow

5 / 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

6 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Cooling down the core temperature

Controlling radiation levels in the environment

Moving water from one location to another

7 / 15

A heat exchanger is a component that:

Only transfers heat to a hotter substance

Transfers heat between two substances at different temperatures

Cools down substances to the same temperature

Stops the flow of heat altogether

8 / 15

Steam, in its purest form, is:

A liquid

A completely invisible gas

A solid

A white mist seen above boiling water

9 / 15

What is the chemical formula for water?

CO2

H2O

10 / 15

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

Only moving water

Using basic components in different combinations

Avoiding the use of steam

Creating new components

11 / 15

Why is steam used in a steam engine?

Because of water's high freezing point

Because of water's high heat of vaporization

Due to its ability to condense quickly

Due to its low heat of vaporization

12 / 15

In forced convection:

The fluid remains stationary, allowing heat transfer

Heat is transferred only through natural circulation

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

The fluid relies on buoyancy due to gravity

13 / 15

In most heat exchangers, the higher pressure fluid is:

Inside the tubes

Outside the tubes

On the shell side

Equally distributed

14 / 15

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

Solvent capability

Conductivity

Adhesion

Cohesion

15 / 15

An open cooling water system is characterized by:

Having a surge tank

Not needing any makeup

Being sealed off from the atmosphere

Being open to the atmosphere
