A thin equilateral triangle plate with a = 104.5 cm (as shown below) is immersed parallel to a U = 11.3 m/s stream of air at 20 °C and 1 atm. Assuming Recr = 106 and laminar flow, estimate the drag of this plate. Take the density and dynamic viscosity of air at 20 °C and 1 atm, as pa =1.2 kg/m3 and u = 1.8 x 105 kg/(m s).

The standard sea level value of viscosity coefficient for air is μ = 1.7894×10−5 kg/(m · s) = 3.7373 × 10−7 slug/(ft · s). The wing on a Piper Cherokee general aviation aircraft is rectangular, witha span of 9.75 m and a chord of 1.6 m. The aircraft is flying at cruisingspeed (141 mi/h) at sea level. Assume that the skin-friction drag on thewing can be approximated by the drag on a flat plate of the samedimensions. Calculate the skin-friction drag:a. If the flow were completely laminar (which is not the case in real life)b. If the flow were completely turbulent (which is more realistic)Compare the two results.
