Water flowing through an 8-cm-diameter pipe enters a porous section, as in Fig. 3.10, which allows a uniform radial veloc- ity v, through the wall surfaces for a distance of 1.2 m. If the entrance average velocity V, is 12 m/s, find the exit velocity V, if (a) vw = 15 cm/s out of the pipe walls or (b) V, = 10 cm/s into the pipe. (c) What value of v, will make V2 = 9 m/s?
