Question:

Consider two pressure taps along the wall of a laminar boundary layer as in Fig. P10–87. The fluid is air at 25°C, U₁ = 10.3 m/s, and the static pressure P₁ is 2.44 Pa greater than static pressure P₂, as measured by a very sensitive differential pressure transducer. Is outer flow velocity U₂ greater than, equal to, or less than outer flow velocity U₁? Explain. Estimate U₂.
