A water flow system through a 0.1 m diameter pipe is experiencing turbulent flow with a Reynolds number of 5000. What changes can engineers make to transition this to laminar flow?
💡 Hint: Consider how each variable in the Reynolds number equation can be manipulated.
Given that the density of a fluid is 850 kg/m³ and viscosity is 0.5 mPa·s, calculate the maximum diameter of the pipe that maintains a laminar flow with a velocity of 2 m/s.
💡 Hint: Determine the flow conditions required for laminar status!
