A flow of liquid is streamline if the Reynold number is
- A less than \( 1000 \)
- B greater than \( 1000 \)
- C between \( 2000 \) to \( 3000 \)
- D between \( 4000 \) to \( 5000 \)
Answer & Solution
Correct Answer
(A) less than \( 1000 \)
Step-by-step Solution
Detailed explanation
The Reynolds number is the ratio of inertial forces to viscous forces. It predicts weather the flow will laminar or turbulent.
A flow of liquid is streamline if the Reynolds number should be less than 2000. Therefore, from the given options, only
option (1) satisfies the condition. Thus, a flow of liquid is streamline if the Reynolds number is less than \( 1000 \).
A flow of liquid is streamline if the Reynolds number should be less than 2000. Therefore, from the given options, only
option (1) satisfies the condition. Thus, a flow of liquid is streamline if the Reynolds number is less than \( 1000 \).
