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