A main pipe of cross-sectional area 5.0 cm2 carries water at 2.0m/s to a junction where it splits into Path X (area 1.0 cm2) and Path Y (area 2.5 cm2). Downstream, Path Y divides again into Outlet 2 (area 1.0 cm2, speed 4.0m/s) and Outlet 3 (area 1.5 cm2, speed unknown). The speed of the water in Path Y just before it splits is measured to be 2.8m/s. Calculate the speed of the water in Outlet 3.
