An incompressible fluid is flowing at steady rate in horizontal pipe. From a section, the pipe divides into two horizontal parallel pipes of diameter (d, and d₂) (where d₁ = 4d₂) that run, for a distance of L each and then again join back to a pipe of the original size. For both the parallel pipes, assume the head loss due to friction only and the Darcy-weisbach friction factor to be same. The velocity ratio between bigger and smaller branched pipe is.
