In triangle ABC, the measure of $\angle B$ is 90°, BC = 16 and AC = 20. Triangle DEF is similar to triangle ABC, where vertices D, E and F correspond to vertices A, B and C respectively and each side of triangle DEF is $\frac{1}{2}$the length of the corresponding side of triangle ABC. What is the value of sinF?

The dynamic pressure q generated by a find moving with velocity can be found using the formula $q=\frac{1}{2}n{v}^2$ where n is the constant density of the fluid. An aeronautical engineer uses moving with velocity 1.54v. What is the ratio of the dynamic pressure of the faster fluid to the dynamic pressure of the slower fluid?
