Explanation:
The given data is as follows.
Diameter of pipe, D = 0.01 m
Velocity V = 0.03 m/s
Fluid density = 36.4 
Viscosity = 0.651 Pa-s
Formula to calculate Reynold number is as follows.
Re = 
= 
= 0.01677
Since, Re < 2100. This means that the flow is laminar.
So, for laminar flow in pipes,
Darcy friction factor f = 
= 
= 3816
Thus, we can conclude that the Darcy friction factor value is 3816.
