1. Sketch the expected flow around a sphere if (a) Re ¼ 4, (b) Re ¼ 4000, and (c) 40 000. Identify the separated region, the wake, any laminar or turbulent boundary layers, and the free stream.

2. Describe the flow to be expected around each of the following and estimate the drag coefficient.

(a) Air at 10-C flowing around a 4.1-cm-diameter golf ball traveling at 35 m=s.

(b) A 2-mm-diameter hailstone traveling through air at 210-C at a speed of 5 m=s.

(d) Air at 20-C flowing over an 8-cm-diamter sphere at a speed of 1 m=s.

(e) Air at 0-C moving past a 10-cm-diameter, 4-m-high pole at 2 m=s.
