Q1:

What is the value of Fanning friction factor f ' for smooth pipe at NRe = 106 approximately ?

A 0.003

B 0.01

C 0.1

D 0.3

ANS:A - 0.003

The Fanning friction factor f′f'f′ for a smooth pipe at Re=106\text{Re} = 10^6Re=106 (Reynolds number of 10^6) is approximately 0.003. This value corresponds to the friction factor f′f'f′ used in calculations involving fluid flow in pipes when considering turbulent flow conditions.
