1. If the water pressure is 143 kPa at the bottom of the step, what is its pressure at the top of the step?

Now suppose the cross sectional area of the hose at the top of the step is reduced to half that at the bottom of the step and that the speed of the water at the bottom of the step is 1.20 m/s.

2. What is the speed of the water at the top of the step?

3. What is the pressure at the top of the step?
