10) A shower pipe at the beach that is 10 cm in diameter carrieswater (density 1000 kg/m3 ) up a height of 2.0 m, at which pointthe pipe narrows to 5 cm and continues another 0.50 m up before thewater squires out of the pipe 2.5 m above where it started. Ignoreviscosity.
a) If the water moves at 1.5 m/s in the wider part of the pipe,what is its speed in the narrower part of the pipe?
b) What is the pressure change from the bottom of the pipe tothe top?
c) What was the pressure of thewater at the bottom of the pipe? (Hint: What does the pressure haveto be when the water leaves the pipe and is exposed to theatmosphere?)
