• Miscellaneous - Images and other items that are useful for this course.
• Other websites - Links to websites which provide data and other information useful to students in this course. There were not written by Professor Cimbala. I apologize if the site address changes - this is beyond my control.

Learning Modules - Background and Review Material

• Dimensions, Units, Conversion Factors, and Significant Digits - A general review of dimensions and units, and the different unit systems (English vs. Metric). This learning module is useful for any subject, not just fluid mechanics.
• The Ideal Gas Constant - A general review of the concepts of mol and molecular weight, and the two forms of the ideal gas constant: the universal gas constant and the specific gas constant.
• Some Useful Conversions, Equations, and Constants - Some conversion factors, especially for the troublesome variables such as pound-mass and pound-force, etc.
• Solutions of Ordinary Differential Equations - A general review of how to solve simple ordinary differential equations. This learning module is useful for any subject, not just fluid mechanics.
• Runge-Kutta technique - An Explanation of how the popular fourth-order Runge-Kutta marching technique works, along with the appropriate equations.
