# Consider two pressure taps along the wall of a laminar boundary layer as in Fig. P1087. The fluid is air

## 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, U_{1} = 10.3 m/s, and the static pressure P_{1} is 2.44 Pa greater than static pressure P_{2}, as measured by a very sensitive differential pressure transducer. Is outer flow velocity U_{2} greater than, equal to, or less than outer flow velocity U_{1}? Explain. Estimate U_{2}.
