The drag force, $F_D$, on a sphere kept in a uniform flow field, depends on the diameter of the sphere $D$; flow velocity, $V$, fluid density, $\rho$; and dynamic viscosity, $\mu$. Which of the following options represents the non-dimensional parameters which could be used to analyze this ... $\dfrac{_{\rho}VD}{\mu} \\$ $\dfrac{F_D}{_{\rho}V^3D^3}$ and $\dfrac{\mu}{_{\rho}VD}$

In a laboratory, a flow experiment is performed over a hydraulic structure. The measured values of discharge and velocity are $\text{0.05}$ $m^{3}/s$ and $\text{0.25}$ $m/s$, respectively. If the full scale structure ($30$ times bigger) is subjected to a discharge of ${270}$ $m^{3}/s$, then the time scale (model to full scale) value (up to two decimal places) is _______
