A water jet flows with a velocity of 5 m/s over a flat plate with a characteristic length of 1 m. Calculate and interpret the Reynolds number given viscosity = 0.001 Pa.s. Discuss its implication.
💡 Hint: Use the formula Re = UL/µ and interpret the flow type.
If the flow in a pipe transitions from laminar to turbulent at Reynolds number of 2300, what flow characteristics would you expect around this basic threshold?
💡 Hint: Consider the behavior of particles in the fluid at different flow regimes.
