Air at 70°f flows parallel to a smooth, thin, flat plate at 13.5 ft/s. the plate is 10.6 ft long. determine whether the boundary layer on the plate is most likely laminar, turbulent, or somewhere in between (transitional). calculate the boundary layer thickness at the end of the plate where the boundary layer is laminar everywhere and where the boundary layer is turbulent everywhere (obtained from the one-seventh-power law). the kinematic viscosity of air at 70ºf is ν = 1.643 × 10–4 ft2/s..

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
