State if the following statements are TRUE or FALSE. No explanation is required. Write "True or False" in your answer paper. (a) The Darcy friction factor of a fully-rough turbulent flow is dependent upon Reynolds number and relative roughness. (b) The fully developed velocity profile of a fluid flow exists in the hydrodynamic entrance region of any internal flow pipe. (c) Increasing the roughness of pipe surface increases pressure drop of the fluid flow in pipes operating under all ranges of Reynolds number.
