They already gave it to you. ReX=5E5BlueCB said:Ah, that's completely baffled me now.
Would you happen to know the formula applicable to aerofoils?
Yes. Now you have the right idea. Of course, you didn't have to do it by trial and error. You could have solved algebraically for L. I haven't checked your units, but, if they are correct, please express L with units.BlueCB said:So what, Reynolds number*length = 6*10^5?
I used an online Reynolds number calculator and used the inputs of the initial question in the formula: p*u*L / µ
For (L) I changed the input until the Reynolds number equaled 600,000
(p = 1.1), (v = 180), (L = 0.060606) and (µ = 2*10^-5).
So for the Reynolds number to be 6*10^5, the length of the region of laminar flow must be 0.60606?
Is that correct?
Laminar flow is characterized by smooth and orderly movement of fluid particles in the same direction, while turbulent flow is characterized by chaotic and irregular movement of fluid particles in various directions.
As the flow velocity increases, the likelihood of transition from laminar to turbulent flow also increases. This is because higher velocities result in greater shear forces, causing the fluid to become more turbulent.
The main factors that influence the transition from laminar to turbulent flow include flow velocity, fluid viscosity, surface roughness, and the presence of disturbances such as obstacles or changes in geometry.
The Reynolds number is a dimensionless parameter that represents the ratio of inertial forces to viscous forces in a fluid. When the Reynolds number exceeds a critical value, the flow is more likely to transition from laminar to turbulent.
The transition from laminar to turbulent flow has implications in various engineering and scientific fields such as aerodynamics, fluid mechanics, and heat transfer. Understanding and predicting this transition is crucial for designing efficient and safe systems, as turbulent flows can cause increased drag, energy losses, and structural damage.
