The cross-sectional radius of a pipeline decreases graudally as `r=r_0e^(-alphax)`, where `alpha=0.50ms^-1`, x is the distance from the pipeline inlet. Find the ratio of Reynolds numbers of two cross-sections separated by `Deltax=3.2m`.

The radius of a pipe decreases according to r=r_(o)e^(-propx) , where alpha=0.50m^(-1)andx is the distance of a cross - section from the first end (x=0) . Find the ratio of Reynolds number for two cross -sections lying at the distance of 2m from each other . (take e=2.718)
