Question
In the Blasius equation
stream function:
j is a dímensionless plane
p(x, y)
f(n)
VDUX
Values of f are not given in Table 7.1, but one published
value is f(2.0) = 0.6500. Consider airflow at 6 m/s, 20°C,
and 1 atm past a flat plate. Atx= 1 m, estimate (a) the height
y; (b) the velocity, and (c) the stream function at 7= 2.0.
