Step 1: Explain transitional regime in fully developed turbulent flow. The transitional regime in fluid flow is an unstable state that occurs between laminar and turbulent flow, typically when the Reynolds number is between 2000 and 4000 for pipe flow. In this regime, the flow exhibits intermittent bursts of turbulence within an otherwise laminar flow, making its behavior unpredictable. Step 2: Substantiate "the bigger the better" in fluid mechanics regarding flow in pipes and ducts. "The bigger the better" refers to using larger pipe diameters. For a given flow rate, a larger diameter pipe results in lower flow velocity. This significantly reduces frictional head losses (which are proportional to V² and inversely proportional to $
