For a fluid with a density of 850 kg/m³ and dynamic viscosity of 0.002 Pa.s flowing at a velocity of 1.5 m/s in a pipe with a diameter of 0.1 m, calculate the Reynolds number and state the flow regime.
💡 Hint: Substitute the values carefully in the formula and remember the definitions.
Discuss how varying the diameter of a pipe in a water supply system affects the Reynolds number and potential flow regimes encountered.
💡 Hint: Think about the equations you've learned regarding diameter and flow.
