Consider the steady flow in a water pipe joint shown in the diagram. The areas are: A1 =0 2m2, A2 =0 2m2, and A3 =0 15 m2. In addition, fluid is lost out of a hole at , estimated at a rate of 0 1m3 s. The average speeds at sections and are V1 =5m s and V3 =12m s, respectively. Find the velocity at section .
