General Example: Water flows through the pipe atthe rate of 30 L/s. The absolute pressure at po<strong>in</strong>t A is200 kPa, and the po<strong>in</strong>t B is 8 m higher than po<strong>in</strong>t A.The lower section of pipe has a diameter of 16 cm andthe upper section narrows to a diameter of 10 cm.F<strong>in</strong>d the velocities of the stream at po<strong>in</strong>ts A and B.R = 30 L/s = 0.030 m 3 /sDAR 2 ; R 2A A = (0.08 m) 2 = 0.0201 m 3A B = (0.05 m) 2 = 0.00785 m 38 mAR=30 L/sBvA R1.49 m/s; 3.82 m/sA A3 30.030 m /s R 0.030 m /sv2 220.0201 m A20.00785 mv A = 1.49 m/sv B = 3.82 m/s
