### Question

A high velocity water jet of cross section area and velocity = 35 m/s enters a pipe filled with stagnant water. The diameter of the pipe is 0.32 m. This high velocity water jet entrains additional water front the pipe and the total water leaves the pipe with a velocity 6 m/s as shown in the figure.

The flow rate of entrained water is litre/s (round off to two decimal places) .
