NCSU MAE308 17. Water flows steadily through the large tanks shown where h B =2 m. The diameters of the pipes exiting tanks A and B are 0.03 m and 0.05 m, respectively. Neglecting frictional losses, determine the water depth h A . h h A B A B Q (1)=free surface of tank A, (2)=free jet at exit of pipe from tank A, (3)=free surface of tank B, (4)=free jet at exit of pipe from tank B Q 1 = Q 2 = Q 3 = Q 4 BE (3) to (4) 34 f 34 s 4 2 4 4 3 2 3 3 w w gz v 2 1 p gz v 2 1 p + + + + ρ = + + ρ v 4 =[2g(z 3 -z 4 )] 1/2 =[2(9.087)(2)] 1/2 =6.26 m/s 0123 . 0 ) 05 . 0 ( 4 π ) s / m 26 . 6 ( A v Q 2 4 4 = = = m3/s 4 . 17 ) 03 . 0 ( π ) 0123 . 0 ( 4 D π Q 4 A Q v 2 2 2 2 = = = = m/s BE (1) to (2) 12 f 12 s 2 2 2 2 1 2 1 1 w w gz v 2 1 p gz v 2 1 p + + + + ρ = + + ρ 2 2 A v 2 1 gh = , 4 . 15 ) 4 . 17 ( ) 087 . 9 ( 2 1 v g 2 1 h 2 2 2 A = = = m 18. Water flows from a large tank through a large pipe that splits into two smaller pipes as shown. If viscous effects are negligible, determine the flowrate from the tank and the pressure at point (1). Determine the net horizontal force that the pipe and tank exert on the fluid. -1-
