Foundations Of Engineering

## Overview of this Lesson

This lesson introduces topics that are foundational to studying any engineering topic including fluid mechanics.

• Engineering Analysis: Using calculations so our designs are faster and better
• Knowledge Construction: Getting knowledge down so is useful and it is remembered (forever)
• Prototyping: Running experiments and getting data to test our KC and engineering analysis

## Benefits of this Lesson

• Learn about Wales Woods Model (the easy way to do calcs in the real world)
• Learn foundational concepts: derivative, integral, mass, weight, …
• Learn the ideal gas law
• Learn about KC (knowledge construction)
• Learn the meaning of unit, dimension (primary and secondary)
• Learn how to carry and cancel units with grid method
• Learn how to check an equation for dimensional homogeneity (DH)

## Goals (Results We Intend to Achieve)

• Learners know foundational concepts: derivative, integral, mass, weight, and ideal gas.
• Learners know the Ideal Gas Law
• Learners can give a one-sentence definition of unit, dimension, dimensional homogeneity
