Hello I want someone to answer this question as I have my doubts about this example question. I want to know how 50,000 Reynolds Number satisfies laminar conditions as a laminar flow would be of Reynolds number less than 2,000 and 50,000 is way above 2,000. Can you answer the question and explain how this satisfies the laminar conditions? Consider a water flow (20°C) at v = 0.1 m/s past a flat plate 1m long. Compute the boundary layer thickness in the middle ofthe plate. Assume that the kinematic viscosity of water at 20°Cis equal to 1x10-6 m²/s.The Reynolds number for the middle of the plate is equal to:ReL/2 = 0.1 [m/s] x 0.5 [m] / 1x10-6 [m²/s] = 50 000This satisfies the laminar conditions. The boundary layer thickness istherefore equal to:8≈ 5.0 x 0.5 / (50 000)¹/2 = 0.011 m

Velocity, V = 0.1 m/s Length of flat plate, L = 1 m Kinematic viscosity of the water, v = 10-6 m2/s…

Question

Hello I want someone to answer this question as I have my doubts about this example question. I want to know how 50,000 Reynolds Number satisfies laminar conditions as a laminar flow would be of Reynolds number less than 2,000 and 50,000 is way above 2,000. Can you answer the question and explain how this satisfies the laminar conditions?

Consider a water flow (20°C) at v = 0.1 m/s past a flat plate 1
m long. Compute the boundary layer thickness in the middle of
the plate. Assume that the kinematic viscosity of water at 20°C
is equal to 1x10-6 m²/s.
The Reynolds number for the middle of the plate is equal to:
ReL/2 = 0.1 [m/s] x 0.5 [m] / 1x10-6 [m²/s] = 50 000
This satisfies the laminar conditions. The boundary layer thickness is
therefore equal to:
8≈ 5.0 x 0.5 / (50 000)¹/2 = 0.011 m
