मान्यताएँ: स्थिर, रुद्धोष्म, उत्क्रमणीय (समदैविक), 1D प्रवाह, नगण्य श्यान प्रभाव।
चरण 1: ऊर्जा समीकरण
स्थिर प्रवाह ऊर्जा समीकरण है:
\( \frac{v^2}{2} + \int \frac{dP}{\rho} + gz = \text{constant} \)
चरण 2: रुद्धोष्म प्रक्रिया
एक उत्क्रमणीय रुद्धोष्म (समदैविक) प्रक्रिया के लिए:
\( P \rho^{-\gamma} = \text{constant} \Rightarrow P = K \rho^\gamma \)
चरण 3: दाब पद का मूल्यांकन
\( \int \frac{dP}{\rho} = \frac{\gamma}{\gamma - 1} \cdot \frac{P}{\rho} \)
चरण 4: ऊर्जा समीकरण में प्रतिस्थापित करें
\( \frac{v^2}{2} + \frac{\gamma}{\gamma - 1} \cdot \frac{P}{\rho} + gz = \text{constant} \)
\( g \) से विभाजित करें:
\( \frac{P}{(\gamma - 1)\rho g} + \frac{v^2}{2g} + z = \text{constant} \)
