What will be the nature of flow of water from a circular tap, when its flow rate increased from \(0.18\, L / min\) to \(0.48\, L / min\) ? The radius of the tap and viscosity of water are \(0.5\, cm\) and \(10^{-3}\, Pa s\), respectively. (Density of water : \(10^{3}\, kg / m ^{3}\) )
- A Unsteady to steady flow
- B Remains steady flow
- C Remains turbulent flow
- D Steady flow to unsteady flow
Answer & Solution
Correct Answer
(D) Steady flow to unsteady flow
Step-by-step Solution
Detailed explanation
The nature of flow is determined by Reynolds Number. \(R _{ e }=\frac{\rho vD }{\eta}\) \([\rho \rightarrow\) density of fluid ; \(\eta \rightarrow\) coefficient of ; \(v \rightarrow\) velocity of flow ; \(D \rightarrow\) Diameter of pipe\(]\) From NCERT If…
