Give me your thoughts in the inverse proportionality between bulk velocity of a liquid flowing inside a pipe and its friction factor (and consequently, its skin friction energy loss). Effectively, for a fixed pipe length and diameter, the Fanning friction factor and the head loss due to friction decreases as the bulk velocity of the liquid increases. Explain this phenomena scientifically.
