An incompressible liquid is flowing through the horizontal pipe as shown in the figure. Pipe 1 is connected to the pipe 2 and pipe 3. The flow of liquid through the pipe 1, pipe 2 and pipe 3 are 8 m/s,6 m/s and 1.1 m/s respectively. If cross-section area of pipe 1 and pipe 2 are 1 m2 and 0.8 m2, find the area of cross-section of pipe 3.
