FUN 2 EO: 1.4-f

1 / 15

In most heat exchangers, the higher pressure fluid is:

Equally distributed

Inside the tubes

Outside the tubes

On the shell side

2 / 15

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

Conductivity

Cohesion

Solvent capability

Adhesion

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

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

Natural circulation and forceful circulation

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

5 / 15

What is the chemical formula for water?

CO2

H2O

6 / 15

Natural convection relies on which driving force?

Pressure

Buoyancy due to fluid density differences

Temperature change

Pumping mechanism

7 / 15

Most of the heat exchangers in the plant are:

Crossflow

Parallel flow

Turbulent flow

Counter flow

8 / 15

In forced convection:

The fluid remains stationary, allowing heat transfer

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

9 / 15

Which of the following statements is true about metals?

Metals are poor conductors because of their ionic bonds

Metals do not form a crystalline structure

Metals do not have free-moving electrons

Metals are usually the best conductors of thermal energy

10 / 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

11 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A completely invisible gas

A liquid

A solid

12 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Moving water from one location to another

Cooling down the core temperature

Controlling radiation levels in the environment

13 / 15

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

Creating new components

Using basic components in different combinations

Only moving water

Avoiding the use of steam

14 / 15

An open cooling water system is characterized by:

Not needing any makeup

Being sealed off from the atmosphere

Having a surge tank

Being open to the atmosphere

15 / 15

The boiling point of water at sea level is:

154 °F

212 °F

180 °F

39.16 °F
