FUN 2 EO: 1.4-f

1 / 15

In forced convection:

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

Heat is transferred only through natural circulation

The fluid remains stationary, allowing heat transfer

The fluid relies on buoyancy due to gravity

2 / 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

3 / 15

Most of the heat exchangers in the plant are:

Parallel flow

Turbulent flow

Counter flow

Crossflow

4 / 15

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

Avoiding the use of steam

Using basic components in different combinations

Only moving water

Creating new components

5 / 15

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

Transfer of heat in a solid and in a vacuum

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

Ionic and covalent bonding

Natural circulation and forceful circulation

6 / 15

Which of the following statements is true about metals?

Metals are usually the best conductors of thermal energy

Metals do not have free-moving electrons

Metals are poor conductors because of their ionic bonds

Metals do not form a crystalline structure

7 / 15

In most heat exchangers, the higher pressure fluid is:

On the shell side

Outside the tubes

Equally distributed

Inside the tubes

8 / 15

The boiling point of water at sea level is:

212 °F

154 °F

39.16 °F

180 °F

9 / 15

Steam, in its purest form, is:

A liquid

A solid

A white mist seen above boiling water

A completely invisible gas

10 / 15

Natural convection relies on which driving force?

Pressure

Temperature change

Buoyancy due to fluid density differences

Pumping mechanism

11 / 15

A heat exchanger is a component that:

Cools down substances to the same temperature

Transfers heat between two substances at different temperatures

Stops the flow of heat altogether

Only transfers heat to a hotter substance

12 / 15

An open cooling water system is characterized by:

Being sealed off from the atmosphere

Being open to the atmosphere

Having a surge tank

Not needing any makeup

13 / 15

What is the chemical formula for water?

H2O

CO2

14 / 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

15 / 15

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

Adhesion

Solvent capability

Cohesion

Conductivity
