3) Water is moving with a velocity of 5.0 m/s through a pipe with a cross-sectional area of 4.0 cm?. The water gradually descends 10 m as the pipe increases in area to 8.0 cm?. What is the speed of flow at the lower level? If the pressure at the upper level is 1.5 x 105 Pa, what is the pressure at the lower level? Ans: 2.5 m/s; 2.6x105 Pa
