The optimum performance of mixing blades $0.5\mathrm{m}$ in diameter is to be tested using a model one-fourth the size of the prototype. (Figure 1) Figure 1 of 1 If the test of the model in water reveals the optimum speed to be $6.5\mathrm{rad}/\mathrm{s}$, dececinine the optimum angular speed of the prototype whon it is used to mix ectyl alcohol. Take $T^2=20^{?}\mathrm{C},V_{h=}=1.51\left(10^6\right){\mathrm{m}}^2/\mathrm{s}$ and $Y_e=1.00\left(10^{?6}\right){\mathrm{m}}^2/\mathrm{s}$ Exprest your answer using three significant figures.
