FUN 2 EO: 1.4-f

1 / 15

The boiling point of water at sea level is:

212 °F

180 °F

39.16 °F

154 °F

2 / 15

In forced convection:

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

The fluid remains stationary, allowing heat transfer

The fluid relies on buoyancy due to gravity

Heat is transferred only through natural circulation

3 / 15

Steam, in its purest form, is:

A completely invisible gas

A solid

A liquid

A white mist seen above boiling water

4 / 15

A heat exchanger is a component that:

Cools down substances to the same temperature

Only transfers heat to a hotter substance

Transfers heat between two substances at different temperatures

Stops the flow of heat altogether

5 / 15

An open cooling water system is characterized by:

Being open to the atmosphere

Being sealed off from the atmosphere

Having a surge tank

Not needing any makeup

6 / 15

What is the fundamental action of the plant?

Cooling down the core temperature

Generating steam from pure water

Controlling radiation levels in the environment

Moving water from one location to another

7 / 15

Why is steam used in a steam engine?

Because of water's high heat of vaporization

Because of water's high freezing point

Due to its low heat of vaporization

Due to its ability to condense quickly

8 / 15

Most of the heat exchangers in the plant are:

Crossflow

Parallel flow

Counter flow

Turbulent flow

9 / 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

10 / 15

Which of the following statements is true about metals?

Metals do not have free-moving electrons

Metals do not form a crystalline structure

Metals are usually the best conductors of thermal energy

Metals are poor conductors because of their ionic bonds

11 / 15

What is the chemical formula for water?

CO2

H2O

12 / 15

In most heat exchangers, the higher pressure fluid is:

Equally distributed

On the shell side

Outside the tubes

Inside the tubes

13 / 15

Natural convection relies on which driving force?

Buoyancy due to fluid density differences

Pressure

Pumping mechanism

Temperature change

14 / 15

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

Solvent capability

Adhesion

Cohesion

Conductivity

15 / 15

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

Creating new components

Only moving water

Avoiding the use of steam

Using basic components in different combinations
