Answer 1

Step-by-step explanation:

Given The thickness of the laminar boundary layers from on a flat plate at points P is 8 cm and at point Q which is 2 cm downstream from point P is 10 cm respectively. The distance of the point P when measured from the leading edge of the plate is

• So thickness of a boundary layer on a flat plate is 8 cm
• So ΔP = 8 cm
• So ΔQ = 10 cm
• So from the relation Δ is proportional to x^1
• Therefore ΔP / ΔQ = x^1 P / x^1 Q
• Distance of  P from the leading edge of the plate will be
•       Or 8 / 10 = (x – 2)^1 / x^1
•        Or 8x = 10 (x – 2)
•            8x = 10 x – 20
•          Or – 2x = - 20
•         Or x = 10 m
