Fanning's coefficient of friction f = 16/Re.
Darcy's friction factor f = 64/Re.
Darcy's friction factor f = 64/Re.

It's the darcy's Coeff of friction.
For viscous-16/Re.
Turbulent-0.0791/Re.
For viscous-16/Re.
Turbulent-0.0791/Re.

Coefficient of friction (f) = 16/Re.
Friction factor = 64/Re.
Friction factor = 64/Re.

For friction loss in laminar flow f=64/Re.
Please verify it.
Please verify it.

You are right my friend.
The equation is 4f = 64/Re.
The equation is 4f = 64/Re.

@Bharat.
Its Only f=64/Re.
Not 4f.
Its Only f=64/Re.
Not 4f.

4f = 64/Re.
=>f=16/Re answer.
=>f=16/Re answer.
