FUN 2 EO: 1.4-f

1 / 15

In forced convection:

The fluid relies on buoyancy due to gravity

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

2 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Cooling down the core temperature

Moving water from one location to another

Controlling radiation levels in the environment

3 / 15

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

Solvent capability

Cohesion

Adhesion

Conductivity

4 / 15

Natural convection relies on which driving force?

Pressure

Pumping mechanism

Temperature change

Buoyancy due to fluid density differences

5 / 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

6 / 15

What is the chemical formula for water?

H2O

CO2

7 / 15

Which of the following statements is true about metals?

Metals do not have free-moving electrons

Metals are usually the best conductors of thermal energy

Metals do not form a crystalline structure

Metals are poor conductors because of their ionic bonds

8 / 15

The boiling point of water at sea level is:

154 °F

212 °F

39.16 °F

180 °F

9 / 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

10 / 15

In most heat exchangers, the higher pressure fluid is:

On the shell side

Inside the tubes

Outside the tubes

Equally distributed

11 / 15

Why is steam used in a steam engine?

Because of water's high heat of vaporization

Due to its low heat of vaporization

Because of water's high freezing point

Due to its ability to condense quickly

12 / 15

Most of the heat exchangers in the plant are:

Counter flow

Turbulent flow

Parallel flow

Crossflow

13 / 15

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

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

Natural circulation and forceful circulation

14 / 15

Steam, in its purest form, is:

A liquid

A completely invisible gas

A white mist seen above boiling water

A solid

15 / 15

An open cooling water system is characterized by:

Having a surge tank

Being sealed off from the atmosphere

Not needing any makeup

Being open to the atmosphere
