critical Reynolds number is defined as the

Which

of the following is true for turbulent flow

Which

of the following is true for laminar flow?

There

is a fluid moving with a certain velocity inside a circular pipe. The nature of

flow was found to be laminar. What should be the nature of flow when we replace

the fluid with a lower viscous fluid and increased its flow rate?

Which of the following is/are true for turbulent flow
