For each statement, choose whether the statement is true or false and discuss your answer briefly. These statements concern a laminar boundary layer on a flat plate (Fig. P10–73C).

(a) At a given x-location, if the Reynolds number were to increase, the boundary layer thickness would also increase.

(b) As outer flow velocity increases, so does the boundary layer thickness.

(c) As the fluid viscosity increases, so does the boundary layer thickness.

(d) As the fluid density increases, so does the boundary layer thickness.
