6.16. CHAPTER 6, PROBLEM 16 547 6.16 Chapter 6, Problem 16 Use a stationary control volume surrounding the main tank as shown in Figure 6.16. Figure 6.16: Cylindrical tank. Because the control volume is stationary, u rel = u , and we can write the mass-conservation principle as d dt 888 V ρ dV ± 1 =0 + 8 s 8 S ρ u · n dS =0 whe reweob se rvetha ttheamoun to fwa te rinthetanki scon s

Unformatted text preview: w U 4 d 2 W , 1 Inlet + w U 4 9 4 d 2 W , 1 Outlet A + w U 4 16 25 d 2 W , 1 Outlet B = 0 Simplifying and dividing through by Ud 2 / 4 , 1 + 9 4 + 16 25 = 0 which tells us that = 100 225 64 Finally, if = 3 / 5 , then = 100 135 64 = 35 64 This means the outlet velocity is less than zero. Hence, fluid enters at Outlet B with a speed of 35 64 U ....
