Water flows from a tap of diameter 1.5 cm with \(7.5 \times 10^{-5} \mathrm{~m}^3 \mathrm{~s}^{-1}\) Coefficient of Viscosity of water is \(10^{-3}\) Pas. The flow is
- A Turbulent with Reynolds number less than 6000
- B Steady flow with Reynolds number less than 2000
- C Turbulent with Reynolds number greater than 6000
- D Steady flow with Reynolds number more than 6000
Answer & Solution
Correct Answer
(C) Turbulent with Reynolds number greater than 6000
Step-by-step Solution
Detailed explanation
\(\mathrm{D}=1.5 \mathrm{~cm}, \mathrm{Q}=7.5 \times 10^{-5} \mathrm{~m}^3 / \mathrm{s}, \eta=10^{-3} \mathrm{Pas}\) \(Q=A v \Rightarrow \frac{\pi}{4} D^2 v \Rightarrow v=\frac{4 Q}{\pi D^2}\) \(\therefore\) Reynold's number,…
