Assume now that the boundary layer development up to a certain point, say x = x1, is given as: at x=x12 ue(x1):U1 and 6(x1):6?1 Now the task is to determine the required development of the external ow downstream of x = x1, such that the boundary layer is continuously on the edge of separation, which implies that i has the constant value /l sep for x > x1. - Use the results of part (a) to show that the required ue(x) can be written as: ue : 1+xx1 mm\" U1 C - Express the value of me], in relation to 1 WP and relate the length scale C to the boundary layer properties at x1. - In addition, derive the corresponding equation for the momentum thickness and express it in the form (6/602
