Problem 1: What is a fluid? Give examples of both fluids and non-fluids. How do they differ?

Problem 2: What is drag?

Problem 3: What is meant by the "no-slip" condition?

Problem 4: What is the Reynolds number? Give the defining equation, and explain the meaning of each term. What is the physical significance of the numerator? The denominator?

Problem 5: Calculate the Reynolds number for the flow of air over a golf ball. The ball has a diameter of 1.69 inches and travels at 200ft/s. Is the flow laminar or turbulent?

Problem 6: What is meant by the concept of similarity? How does this relate to the Reynolds number?

Problem 7: What is the "law of drag" at low Reynolds number?

Problem 8: Estimate the force on your hand when you hand when you hold it out your car window while driving 55 mph. Repeat the calculation if you were to hold your hand out of the window of an airplane flying 550 mph.
