Question:

Water is moving with a speed of 5.0 m/s through a pipe with a cross-sectional area of 4.0 cm2. The water gradually descends 10 m as the pipe cross-sectional area increases to 8.0 cm2.

(a) What is the speed at the lower level?

(b) If the pressure at the upper level is 1.5 x 105 Pa, what is the pressure at the lower level?
