Question Statement:
The relative span of a droplet size spectrum is defined as $\text{Span} = \frac{D_{v0.9} - D_{v0.1}}{D_{v0.5}}$. For a hydraulic nozzle with $D_{v0.9} = 350\text{ \mu m}$, $D_{v0.1} = 150\text{ \mu m}$, and $D_{v0.5} = 200\text{ \mu m}$, the relative span $\frac{350 - 150}{200}$ is:
