Question

**Problem 1: Streamlining**

From dimensional analysis, we know the drag force is \( F_D = C_D \rho A V^2 / 2 \), where \( C_D \) is a dimensionless coefficient of drag. The two space shuttles below have the same area \( A \), the same velocity \( V \), and are flying through the same air. Which has a smaller \( C_D \) and why? (≤25 words)

[Images: Two space shuttles are shown; the first shuttle is streamlined with a sleeker shape, and the second shuttle appears less streamlined with more surface unevenness.]

Explanation: The shuttle with the sleeker, more aerodynamic design likely has a smaller \( C_D \) due to reduced air resistance.

The drag force on a submarine, which is moving on the surface, is to be determined by a test on a model which is scaled down to one-twentieth of the prototype. The test is to be carried in a towing tank, where the model submarine is moved along a channel of liquid. The density and the kinematic viscosity of the seawater are 1010 kg/m³ and 1.3x10-6 m 2/s, respectively. The speed of the prototype is 2.6 m/s. Assume that F = f(V, L. g. p.), using pi-theorem and similarity principle to: a) Determine the speed at which the model should be moved in the towing tank. b) Determine the kinematic viscosity of the liquid that should be used in the towing tank.

4. The Wright brothers used a very thin wing on their 1903 flyer. In addition, they made extensive use of a homebuilt wind tunnel to test their wing designs. span, b chord, c Model of Wright Flyer (a) The Wright's wind-tunnel models had chord length, c, of about 0.04 m and wing span (length) of 0.26 m. The wind tunnel operated at approximately the same wind speed as the full-scale aircraft - about 13 m/s. Estimate the drag (friction) of a single wind-tunnel model wing under standard conditions (o = 1.225 kg/m³, = 1.7894 x 10-³ kg/s-m). Note that the wing is mounted in the wind tunnel so that both upper and lower surfaces are exposed to the flow. (b) The full-scale 1903 flyer had a chord length of 1.9 m and a wing span of 12.3 m. Estimate the drag (friction) of a single full-scale Wright flyer wing flying at 13 m/s under standard atmospheric conditions.
