Which of the following statement is TRUE? (A) Large-scale turbulentmotion is roughly dependent of viscosity. In other words, at high Reynolds numbers, viscous forces, which contribute to flow stability, are significant compared to inertial forces that contribute to flow instability. (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.
