Solution: The average velocity U of a fluid flowing through a passage is related to cross-sectional area (A) and volume flow rate (V dot) by the expression V dot=UA. Combine this expression, the formula for Reynolds number, and the formula for area of a circle to develop a symbolic algebraic expression for the Reynolds number of flow through a passage of cirrcular cross-section. Your expression should be in terms of diameter, volume flowrate, and fluid properties. A garden hose with an inside diameter of 5/8 inch is supplying water at a rate of 3 gallons per minute. What is the Reynolds number of the flow? Is the flow laminar or turbulent?
