Scientific Basis and Formulas

The Bernoulli’s Equation Calculator is grounded in fluid mechanics, specifically Bernoulli’s principle, which describes energy conservation in a moving fluid. The key formula is:

• Bernoulli’s Equation: \( P + \frac{1}{2} \rho v^2 + \rho g h = \text{constant} \), where \( P \) is pressure (Pa), \( \rho \) is fluid density (kg/m³), \( v \) is velocity (m/s), \( g \) is gravitational acceleration (m/s²), and \( h \) is height (m).
• Solving for Pressure: \( P_2 = P_1 + \frac{1}{2} \rho (v_1^2 - v_2^2) + \rho g (h_1 - h_2) \).
• Solving for Velocity: \( v_2 = \sqrt{v_1^2 + \frac{2}{\rho} (P_1 - P_2 + \rho g (h_1 - h_2))} \).
• Solving for Height: \( h_2 = h_1 + \frac{P_1 - P_2 + \frac{1}{2} \rho (v_1^2 - v_2^2)}{\rho g} \).

These formulas are derived from fluid dynamics theory, validated through peer-reviewed literature, and detailed in the Bernoulli’s Equation Wikipedia page. The calculator validates inputs to ensure numerical accuracy and handles edge cases like negative velocity squared.
