a) A sphere (Case 1) is modified with a fairing at the back of sphere (Case 2) and a housing (Case 3) to make it more streamline as shown in Figure 1. By assuming the turbulent flow condition for all cases:   Draw the flow profile for each case,   Discuss the effect of modification using fairing and housing on the (1) friction drag, (2) pressure drag, and (3) total drag.
