Consider a boundary layer growing along a thin flat plate. The boundary layer thickness, d, is a function of the downstream distance x, free-stream velocity V, fluid density ρ, and dynamic viscosity μ.   Which of the following answers is NOT the correct dimensionless parameters representing this physical phenomenon?

Group of answer choices

(ρ*V*d^2)/(μ*x) , d/x

x/d , (ρ*V*d)/μ

d/x , (ρ*V*x)/μ

(ρ*V*d)/μ , (ρ*V*x)/μ

Answer #1

The dimensional parameter that is not correct is (e) (fuxl. This to not correct because it has dimension [ L-] . And to be dI am pretty sure of the answer. Please dear thumpsup for the answer. Thank you.
