Strength Of Materials
4. Consider two scenarios. In both scenarios a baseball surrounded by fluid is pushed to the right for 5 seconds, sees no forces for the next 10 seconds, then is pushed to the left for 5 seconds. In one scenario the Reynolds number is 0.001 and the other the Reynolds number is 1000. Explain what happens to the baseball in each scenario (particularly comparing and contrasting where the baseball ends up and how much momentum it has after the 20 second period.) Also explain what would have to be different for the same baseball to experience flows with such different Reynolds number values.
