(B) Flow far from the surface of a solid object is inviscid. Effects of viscosity are manifest only in a thin layer near the surface where steep velocity gradients occur Velocity profile of Newtonian fluids in laminar flow is flatter than that in turbulent flow D Average fluid velocity of Newtonian fluids in laminar flow inside a circular pipe is twice the maximum fluid velocity E Flow inside an eddy is turbulent because of its large size.

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.
