Verify that the flow is turbulent.
The mechanical-energy balance provides a basis for estimating pressure drop owing to friction in fluid flow. For steady flow of an incompressible fluid in a horizontal pipe of constant cross-sectional area, it may be written,
where 
is the Fanning friction factor. Churchill gives the following expression for 
for turbulent flow:
Here, Re is the Reynolds number and ? /D is the dimensionless pipe roughness. For pipe flow, Re ? u?D/?, where D is pipe diameter and ? is dynamic viscosity. The flow is turbulent for Re > 3000.
Consider the flow of liquid water at 25°C. For one of the sets of conditions given below, determine
