For the following questions, Circle the correct answer Q1. We have a steady fully rough turbulent flow of water with constant density in a cylindrical pipe of constant diameter. The height of the uniform roughness elements in the pipe is k.. . . For a fully developed rough turbulent flow in the pipe, the condition ku. -> 70 is the same as k,> 66,. [True/False] V avg The wall shear stress T-pfU/8. It is applicable only for steady fully rough turbulent flow in the pipe. [True/False] The shear stress distribution is linear with the radial distance from the pipe centerline only for laminar flow. [True/False] The head loss per unit length is quadrupled when the discharge is doubled. [True/False] The piezometric pressure drops uniformly along the pipe because the flow is steady along the pipe [True/False]
