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 graduall 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  105 Pa, what is the pressure at the lower level?
