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

Natural circulation and forceful circulation

Ionic and covalent bonding

Transfer of heat in a solid and in a vacuum

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

2 / 15

What is the chemical formula for water?

CO2

H2O

3 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A liquid

A solid

A completely invisible gas

4 / 15

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

Using basic components in different combinations

Creating new components

Avoiding the use of steam

Only moving water

5 / 15

Natural convection relies on which driving force?

Pressure

Temperature change

Pumping mechanism

Buoyancy due to fluid density differences

6 / 15

The boiling point of water at sea level is:

39.16 °F

180 °F

212 °F

154 °F

7 / 15

Why is steam used in a steam engine?

Due to its low heat of vaporization

Due to its ability to condense quickly

Because of water's high freezing point

Because of water's high heat of vaporization

8 / 15

An open cooling water system is characterized by:

Not needing any makeup

Being open to the atmosphere

Having a surge tank

Being sealed off from the atmosphere

9 / 15

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

Cohesion

Conductivity

Solvent capability

Adhesion

10 / 15

What is the fundamental action of the plant?

Controlling radiation levels in the environment

Generating steam from pure water

Moving water from one location to another

Cooling down the core temperature

11 / 15

Most of the heat exchangers in the plant are:

Crossflow

Parallel flow

Turbulent flow

Counter flow

12 / 15

Which of the following statements is true about metals?

Metals are poor conductors because of their ionic bonds

Metals are usually the best conductors of thermal energy

Metals do not form a crystalline structure

Metals do not have free-moving electrons

13 / 15

In most heat exchangers, the higher pressure fluid is:

Equally distributed

Inside the tubes

On the shell side

Outside the tubes

14 / 15

A heat exchanger is a component that:

Stops the flow of heat altogether

Cools down substances to the same temperature

Only transfers heat to a hotter substance

Transfers heat between two substances at different temperatures

15 / 15

In forced convection:

The fluid remains stationary, allowing heat transfer

The fluid relies on buoyancy due to gravity

Heat is transferred only through natural circulation

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