An approximation for the boundary-layer shape in Figs. 1.5 b and P1.51 is the formula u( y) < U sina y 2 b, 0 # y # where U is the stream velocity far from the wall and is the boundary layer thickness, as in Fig. P1.51. If the fl uid is helium at 20 8 C and 1 atm, and if U 5 10.8 m/s and 5 3 cm, use the formula to ( a ) estimate the wall shear stress w in Pa, and ( b ) fi nd the position in the boundary layer where is one-half of w .
