Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
क्रांतिक प्रवाह के लिए, y = yc
क्रांतिक प्रवाह पर विशिष्ट ऊर्जा, Ec
\({E_c} = {y_c} + \frac{{V_c^2}}{{2g}}\)
\({E_c} = {y_c} + \frac{{Q_c^2}}{{2gA_c^2}}\)
क्रांतिक प्रवाह के लिए:
\(\frac{{{Q^2}T}}{{gA_c^3}} = 1 \Rightarrow \frac{{{Q^2}}}{{gA_c^2}} = \frac{{{A_c}}}{T}\)
( T = B)
रखें, \(A = \frac{1}{2} \times Base \times Height\)
\({E_c} = {y_c} + \frac{{{A_c}}}{{2T}} = {y_c} + \frac{{0.5 \times B \times {y_c}}}{{2 \times B}} = {y_c} + \frac{{{y_c}}}{4}\)
∴ \(\frac{{{y_c}}}{{{E_c}}} = \frac{4}{5}\)
