Question

Water at 20-C ?ows over a 3-m long and 2-m wide ?at plate at 3 m=s. Assume a turbulent ?ow from the leading edge (a trip wire at the leading edge can be used to cause the turbulence) and calculate:

(a) d at x ¼ 3 m.

(b) t0 at x ¼ 3 m.

(c) The drag force on one side of the plate.

(d) The displacement and momentum thicknesses at x ¼ 3 m.

(e) The shear velocity and the viscous wall-layer thickness.
