A fluid is to be carried in a 125-mm-diameter copper pipe such that the Reynolds number of the flow is equal to 5 × 104 . The pipe is highly polished, and it can be assumed that ks ≈ 0. Using the given data, estimate the thickness of the viscous boundary layer adjacent to the pipe surface. Is the flow turbulent? Is the flow fully turbulent?
