Chapter 8, Problem 8.45(choose chapter or problem)
A student is competing in a contest to design a radio-controlled blimp. The drag force acting on the blimp depends on the Reynolds number, Re = (p VD)/IJ-, where Vis the speed of the blimp, Dis the maximum diameter, pis the density of air, and ~is the viscosity of air. This blimp has a coefficient of drag ( CfJ) of 0.3. This 1r-group is defined as Fo Co= 2 pV2Ap where F0 is the drag force p is the density of ambient air, Vis the speed of the blimp, and Ap = 1TD2 /4 is the maximun1 section area of the blimp from a front view. Calculate the Reynolds number, the drag force in newtons, and the power in watts required to move the blimp through the air. Blimp speed is 800 mm/s, and the maximum diameter is 475 mm. Assume that ambient air is at 20C.
