Question

If the friction factor of the laminar flow through a circular pipe is 0.1 then reynolds number of the flow will be

Answer 1

Answer:

We know that the formulae of the friction factor for laminar air flow is written as f = 64/RN in which the RN is the Reynolds number.

From the question we get to know that the friction factor given is 0.1 of the laminar flow through circular pipe then on putting the values we will get that.

f = 64/RN.  

0.1 = 64/RN.

RN = 64/0.1 which will be equal to 640.  

It is always justified that the laminar flow for stream line flow will always be less than 2300 and will be independent of the frictional flow of the pipes and other things.
