Water flowing through an 8-cm-diameter pipe enters a porous section, as shown in the figure, which allows a uniform radial velocity distribution vw? through the wall surfaces for a distance of 1.2m. If the average entrance velocity V1? is 12m/s, find the average exit velocity V2?, if vw?=15cm/s out of the pipe.
