How to Apply Units

Overview of Lesson

Learning fluid mechanics (or any subject) is easier if we think with units because this provides a connection to the real world. In addition, applying units has other benefits. For example,

  • saves time because we spot errors
  • makes professional documentation easier to follow
  • help us use reasoning to solve problems

Thus, units are useful for learning and for doing tasks and projects.

Benefits of this lesson

  • Learn the meaning of units, measurement, and dimensions
  • Learn how to connect a unit to your everyday world
  • Learn how to check an equation for dimensional homogeneity
  • Learn how to carry and cancel units with the grid method
  • Learn how to reason out a solution to a problem by using units
