Consider a 0.38m long vertical plate that is at 70°C. The plate is suspended in quiescent air that is at 25°C. Estimate the velocity boundary layer thickness and maximum upward velocity at the trailing edge of the plate. How does the boundary layer thickness compare with the thickness that would exist if the air were flowing over the plate at a free stream velocity of 6.8 m/s?

Question

Consider a 0.38m long vertical plate that is at 70°C. The plate is suspended in quiescent
air that is at 25°C. Estimate the velocity boundary layer thickness and maximum upward
velocity at the trailing edge of the plate. How does the boundary layer thickness compare
with the thickness that would exist if the air were flowing over the plate at a free stream
velocity of 6.8 m/s?
