3. Sketch the root locus for the unity feedback system shown in Figure P8.3 for the following transfer functions: [Section: 8.4] a. \( G(s)=\frac{K(s+2)(s+6)}{s^{2}+8 s+25} \) b. \( G(s)=\frac{K\left(s^{2}+4\right)}{\left(s^{2}+1\right)} \) c. \( G(s)=\frac{K\left(s^{2}+1\right)}{s^{2}} \) d. \( G(s)=\frac{K}{(s+1)^{3}(s+4)} \)

(10 pts) Certain thin metallic coatings can be deposited by shooting workpieces with molten metal droplets, which are sprayed from a nozzle and travel through an inert gas shield to prevent oxidation on their way to impact (Fig. 1). If each droplet is modeled as a sphere of diameter \( D=0.0004 \mathrm{~m} \) initially at a temperature of \( T_{0}=1100 \mathrm{~K} \) and moving at \( u=3.75 \mathrm{~m} / \mathrm{s} \) toward the substrate, calculate the droplet's rate of heat loss (in units of \( W \) ) as it exits the nozzle. The gas is at \( T_{\infty}=300 \mathrm{~K} \), for which its properties at this temperature are given by table to the right. The gas viscosity at the (higher) temperature of the molten metal is \( \mu=4.46 \times 10^{-5} \mathrm{~N} \cdot \mathrm{~s} / \mathrm{m}^{2} \). Assume Whitaker's correlation is applicable: \[ \overline{N u_{D}}=2+\left(0.4 R e_{D}^{1 / 2}+0.06 \operatorname{Re}_{D}^{2 / 3}\right) \operatorname{Pr}^{2 / 5}\left(\frac{\mu}{\mu_{s}}\right)^{1 / 4} \] where all parameters are evaluated at \( T_{\infty} \), except \( \mu_{s} \), which is evaluated at the sphere's temperature. Figure 1: Surfacing. \begin{tabular}{ll} \hline var & value \\ \hline\( \mu \) & \( 2 \times 10^{-5} \mathrm{~N} \cdot \mathrm{~s} / \mathrm{m}^{2} \) \\ \( \nu \) & \( 1.22 \times 10^{-4} \mathrm{~m}^{2} / \mathrm{s} \) \\ \( k \) & \( 0.152 \mathrm{~W} /(\mathrm{m} \mathrm{K}) \) \\ \( \operatorname{Pr} \) & 0.68 \\ \hline \end{tabular}
