Pick out the correct statement pertaining to transition/ entrance length
in fluid flow.
(A) The length of entrance region of pipe, in which full development of fluid
flow takes place such that velocity profile does not change downstream, is called
the transition length
(B) Transition length for laminar flow of Newtonian fluids in a pipe of
diameter 'd' is equal to 0.05. D.NRe
(C) Transition length for turbulent flow of Newtonian fluids in a smooth pipe
of diameter 'd' is equal to 50 D
(D) All (A), (B) and (C)
in fluid flow.
