Question: A flat plate 2 0 m long and 5 m wide is placed in an airflow at 2 0 C having a velocity of 4

A flat plate

20

m long and

5

m wide is placed in an airflow at

20 C

having a velocity of

40 \frac{m}{s} .

The streamwise pressure gradient is zero. Assume that the boundary layer on the plate transitions from laminar to turbulent instantaneously at a location where the streamwise Reynolds number

R e_{x} = 3 10^{6} .
