bernoulli's equation

Question

Bernoulli's equation neglects which effect?

RankGuru · Accepted Answer

1. **Bernoulli's Principle**: States that for an ideal fluid flow, the sum of pressure energy, kinetic energy, and potential energy per unit volume is constant: $P + \frac{1}{2} ho v^2 + ho g h = 	ext{const}$.
2. **Assumptions for Ideal Flow**:
   - **Incompressible** (constant density).
   - **Irrotational** (no turbulence).
   - **Non-viscous** (frictionless).
3. **Analysis**: The formula does not include terms for energy dissipation due to internal friction between layers.
4. **Conclusion**: **Viscosity** is neglected in the basic Bernoulli derivation.
