A solar photovoltaic system receives radiations between 400–750 W/m\(^2\). Efficiency = 14%. Cell parameters: \(V_{oc} = 21.6 \, V\), \(I_{sc} = 3.22 \, A\), fill factor = 0.72. Find minimum cell area required to generate 10 kW power.
The ordinates of a 6-hour S-hydrograph of a catchment are given in the table. The catchment has phi-index of 0.25 cm h\(^{-1}\) and baseflow of 10.5 m\(^3\)/s. The peak of the flood hydrograph generated from this catchment due to a storm of 45 mm received during the first 6 h in m\(^3\)/s is: \[ \begin{array}{|c|c|} \hline \text{Time (h)} & 0 6 12 18 24 30 36 42 48
\hline \text{Ordinate (m}^3/s\text{)} & 0 30 90 180 252 306 342 360 360
\hline \end{array} \]
Match the Columns: \[ \begin{array}{|c|c|} \hline I & II
\hline 1. \; \text{Tensiometer} & a. \; \text{Consumptive use}
2. \; \text{Piezometer} & b. \; \text{Bernoulli's equation}
3. \; \text{Lysimeter} & c. \; \text{Soil moisture}
4. \; \text{Elbow meter} & d. \; \text{Hydrostatic pressure}
5. \; \text{Pitot tube} & e. \; \text{Volumetric flow rate}
\hline \end{array} \]
