FUN 2 EO: 1.4-f

1 / 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

Transfer of heat in a solid and in a vacuum

Natural circulation and forceful circulation

Ionic and covalent bonding

2 / 15

In most heat exchangers, the higher pressure fluid is:

Outside the tubes

Equally distributed

On the shell side

Inside the tubes

3 / 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

4 / 15

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

Only moving water

Creating new components

Avoiding the use of steam

Using basic components in different combinations

5 / 15

In forced convection:

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

The fluid relies on buoyancy due to gravity

6 / 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 low heat of vaporization

Due to its ability to condense quickly

7 / 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

8 / 15

What is the fundamental action of the plant?

Moving water from one location to another

Cooling down the core temperature

Generating steam from pure water

Controlling radiation levels in the environment

9 / 15

The boiling point of water at sea level is:

180 °F

154 °F

212 °F

39.16 °F

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

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

Conductivity

Adhesion

Cohesion

Solvent capability

12 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A solid

A liquid

A completely invisible gas

13 / 15

Natural convection relies on which driving force?

Temperature change

Pumping mechanism

Buoyancy due to fluid density differences

Pressure

14 / 15

What is the chemical formula for water?

H2O

CO2

15 / 15

Most of the heat exchangers in the plant are:

Crossflow

Turbulent flow

Parallel flow

Counter flow
