Problem $5$: Consider flow across a long, flat plate. For a$-$d$,$ state whether the statement is true or

false and give a brief statement to explain your

reasoning.

At a given x$-$location, if the Reynolds number

were to decrease, the boundary layer thickness

would increase.

As outer flow velocity increases, so does the

boundary layer thickness.

As the fluid viscosity increases, so does the

boundary layer thickness.

As the fluid density decreases, so does the boundary layer thickness.
