GATE Civil 2012 | Question: 39
The top width and the top depth of flow in a triangular channel were measured as $4$ m and $1$ m, respectively. The measured velocities on the centre line at the water surface, $0.2$ m and $0.8$ m below the surface are $0.7$ m/s, $0.6$ ... Using two-point method of velocity measurement, the discharge (in $m^3/s$) in the channel is $1.4$ $1.2$ $1.0$ $0.8$

In a $5$ m wide rectangular channel, the velocity $u$ distribution in the vertical direction $y$ is given by $u=1.25 y^{\frac{1}{6}}$. The distance $y$ is measured from the channel bed. If the flow depth is $2$ m, the discharge per unit width of the channel is $2.40 \: m^3/s/m$ $2.80 \: m^3/s/m$ $3.27 \: m^3/s/m$ $12.02 \: m^3/s/m$

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 _______
