Q9.11: NCERT Physics - Part 2 MECHANICAL PROPERTIES OF FLUIDS 9.11 Solution: Can Bernoulli's equation be used to describe the flow of water…
⚠️ Common Exam Traps & Conceptual Pitfalls
Bernoulli’s equation is valid only for $steady$, $inviscid$, $streamline$ flow. A rapid is turbulent and viscous, violating these assumptions, so the equation cannot be applied.
Can Bernoulli's equation be used to describe the flow of water through a rapid in a river? Explain.
Step-by-Step Verified Solution
**Answer:** No.
**Step-by-Step Explanation:**
Bernoulli's equation assumes steady, streamline (laminar) flow. In a rapid, the flow is turbulent, with chaotic eddies and significant energy dissipation. Hence, Bernoulli's equation is not applicable.
