Ambient Temperature: Definition & Range

1. Ambient Temperature: Definition & Range

The ambient temperature is determined by the surrounding location. Learn about ambient temperature and how it is defined in outside weather, air-conditioned rooms, and computer rooms.

How to Read Time Temperature Transformation Diagrams

2. How to Read Time Temperature Transformation Diagrams

This lesson defines the terms phase and microstructure, introduces time temperature transformation diagrams, and explains how these diagrams can be used to predict the phases and microstructures present in a material.

Air Cooled Heat Exchanger: Definition & Design

3. Air Cooled Heat Exchanger: Definition & Design

This lesson describes the working principle and design of an air cooled heat exchanger. The fundamental heat transfer equation used for an air-cooled heat exchanger is described and is used to explain the design methodology for designing an air-cooled heat exchanger.

Sensible Cooling: Definition & Load

4. Sensible Cooling: Definition & Load

Sensible cooling is the process of removing heat from air while keeping the moisture constant. Learn about the definition and formula of sensible cooling load, distinguish dry bulb from wet bulb temperature, and explore sensible and latent cooling.

Sensible Heat: Definition, Load & Equation

5. Sensible Heat: Definition, Load & Equation

Sensible heat is the amount of thermal energy that is required to change the temperature of an object. This lesson will look at how sensible heat changes that temperature and the equation that we use to model the temperature change.

Sensible vs. Latent Heat

6. Sensible vs. Latent Heat

In this lesson, the conceptual difference between sensible and latent heat is discussed. Sensible heat is heat that can be measured on a thermometer, while latent heat is the type of heat energy that allows for phase changes, such as those between liquid and gas forms of a substance.

Absolute Humidity: Definition & Equation

7. Absolute Humidity: Definition & Equation

Absolute humidity is the ratio of water vapor mass to dry air mass in a specific air volume. Explore humidity, discover the definition, equation, and example of absolute humidity, and learn about relative and desired humidity.

Absolute Humidity vs. Relative Humidity: Formulas & Conversion

8. Absolute Humidity vs. Relative Humidity: Formulas & Conversion

In this lesson, you will learn the difference between absolute humidity and relative humidity. You will understand how humidity (or moisture content) relates to the composition of air, and the relationship between different ways of representing the humidity level of air.

Thermal Expansion and Contraction

9. Thermal Expansion and Contraction

In this lesson, you'll learn how materials change when temperature changes. You'll also explore how this change is measured and how the coefficient of thermal expansion helps measure this change.

Thermal Gradient: Definition & Calculation

10. Thermal Gradient: Definition & Calculation

Thermal gradients are created when a heat differential exists in some part of an object or area. Examine the different ways to interpret thermal gradient formulas, and learn how heat transfer is not restricted to airflow.
