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 _______
