Q. Water enters a circular pipe of length L = 5.0 m and diameter D = 0.20 m with Reynolds number ReD = 500. The velocity profile at the inlet of the pipe is uniform while it is parabolic at the exit. The Reynolds number at the exit of the pipe is .
Ans: 500
Sol:
Re =ρVD/μ
Reynold’s no. will not change
Re at exit = 500
