Question

Ambient air at 20 degree Celsius flows past a flat plate with a sharp leading edge at 3 m/s. The plate is heated uniformly throughout its entire length and is maintained at a surface temperature of 40 degree Celsius. Calculate the distance from the leading edge at which the flow in the boundary layer changes from laminar to turbulent conditions. Assume that transition occurs at a critical Reynolds number of 500000

Options:

A . 4.67 m

B . 3.67 m

C . 2.67 m

D . 1.67 m

Answer: Option C
Answer: (c).2.67 m
