Water flows horizontally through a garden hose with an inner diameter of .012 m at a speed of 7.8 m/s. it exits out a small nozzle with a diameter of only 0.0085 m. how fast it is travelling out of the nozzle?

Explanation:

The given data is as follows.

Speed of water , = 7.8 m/s

 Inner diameter , = 0.012 m

 Radius, = 0.006 m

 Inner diameter for the second nozzle, = 0.0085 m

Radius, = 0.00425

Now, let us assume that speed of water through the second nozzle be .

Hence, using the equation of continuity  we will find the speed of water through the nozzle as follows.

             0.0002808 =

                = 15.54 m/s

Thus, we can conclude that water is travelling at a speed of 15.54 m/s.
