Question

(b) Energy lost due to turbulence and friction varies with kinetic energy. (c) Pipe roughness affects the friction factor or coefficient. (d) Reynolds number will be higher than 2,000. (e) Flow of gases and high viscosity liquids is usually turbulent.

Step 1

In turbulent flow, the velocity profile is flatter and the velocity at the center of the pipe is nearly the same as the average velocity. (b) The statement is true. Turbulent flow is characterized by eddies and vortices that cause energy loss due to friction. The Show more…
