Walker, Halliday & Resnick — Fluids: Problem 64

64 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 12 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?

📝 Solution Approach

Given: 5.0 m, 4.0 cm, 12 m, 8.0 cm
