FUN 2 EO: 1.4-f

1 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A solid

A liquid

A completely invisible gas

2 / 15

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

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

Natural circulation and forceful circulation

Transfer of heat in a solid and in a vacuum

Ionic and covalent bonding

3 / 15

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

Using basic components in different combinations

Avoiding the use of steam

Only moving water

Creating new components

4 / 15

The boiling point of water at sea level is:

212 °F

39.16 °F

180 °F

154 °F

5 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Moving water from one location to another

Controlling radiation levels in the environment

Cooling down the core temperature

6 / 15

Why is steam used in a steam engine?

Because of water's high freezing point

Due to its low heat of vaporization

Due to its ability to condense quickly

Because of water's high heat of vaporization

7 / 15

A heat exchanger is a component that:

Only transfers heat to a hotter substance

Transfers heat between two substances at different temperatures

Stops the flow of heat altogether

Cools down substances to the same temperature

8 / 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

9 / 15

Natural convection relies on which driving force?

Buoyancy due to fluid density differences

Pumping mechanism

Temperature change

Pressure

10 / 15

In forced convection:

The fluid relies on buoyancy due to gravity

Heat is transferred only through natural circulation

The fluid remains stationary, allowing heat transfer

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

11 / 15

What is the chemical formula for water?

H2O

CO2

12 / 15

Most of the heat exchangers in the plant are:

Counter flow

Parallel flow

Turbulent flow

Crossflow

13 / 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

14 / 15

In most heat exchangers, the higher pressure fluid is:

Outside the tubes

On the shell side

Inside the tubes

Equally distributed

15 / 15

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

Conductivity

Adhesion

Solvent capability

Cohesion
