= Consider the steady flow in a water pipe joint shown in the accompanying diagram. The areas are A = 0.2 m, A = 0.2 m, and A3 0.15 m. In addition, fluid is lost out of a hole at location 4, estimated at a rate of 0.1 m/s. The average velocities at sections 1 and 3 are V = 5 m/s and V3 = 12 m/s, respectively. Find the velocity at section 2. DO
