FUN 2 EO: 1.4-f

1 / 15

In most heat exchangers, the higher pressure fluid is:

On the shell side

Equally distributed

Inside the tubes

Outside the tubes

2 / 15

A heat exchanger is a component that:

Cools down substances to the same temperature

Transfers heat between two substances at different temperatures

Only transfers heat to a hotter substance

Stops the flow of heat altogether

3 / 15

Natural convection relies on which driving force?

Pumping mechanism

Temperature change

Buoyancy due to fluid density differences

Pressure

4 / 15

What is the fundamental action of the plant?

Moving water from one location to another

Cooling down the core temperature

Controlling radiation levels in the environment

Generating steam from pure water

5 / 15

The boiling point of water at sea level is:

39.16 °F

212 °F

154 °F

180 °F

6 / 15

Most of the heat exchangers in the plant are:

Counter flow

Crossflow

Turbulent flow

Parallel flow

7 / 15

Which of the following statements is true about metals?

Metals do not form a crystalline structure

Metals are poor conductors because of their ionic bonds

Metals are usually the best conductors of thermal energy

Metals do not have free-moving electrons

8 / 15

Why is steam used in a steam engine?

Because of water's high heat of vaporization

Due to its ability to condense quickly

Due to its low heat of vaporization

Because of water's high freezing point

9 / 15

An open cooling water system is characterized by:

Being open to the atmosphere

Having a surge tank

Not needing any makeup

Being sealed off from the atmosphere

10 / 15

What is the chemical formula for water?

H2O

CO2

11 / 15

In forced convection:

Heat is transferred only through natural circulation

The fluid relies on buoyancy due to gravity

The fluid remains stationary, allowing heat transfer

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

12 / 15

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

Avoiding the use of steam

Only moving water

Creating new components

Using basic components in different combinations

13 / 15

Steam, in its purest form, is:

A liquid

A completely invisible gas

A solid

A white mist seen above boiling water

14 / 15

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

Solvent capability

Adhesion

Cohesion

Conductivity

15 / 15

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

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

Natural circulation and forceful circulation
