A boundary layer is a thin region $($usually along a wall$)$ in which viscous forces are

significant and within which the flow is rotational. Consider a boundary layer growing

along a thin flat plate, as shown in Figure $5.$ The flow is steady. The boundary layer

hickness $8$ at any downstream distance x is a function of x$,$ free$-$stream velocity Vo

density p and viscosity u$.$ Use the method of repeating variables to generate

dimensionless relationship for & as a function of the other parameters. Show all your

work.
