Water is moving having a speed of 5.0 m/s via a pipe of cross-sectional area of 4.0 cm2. The water slowly descends 10 m as the pipe cross-sectional area rises to 8.0 cm2.
i) Determine the speed at the lower level?
ii) When the pressure at the upper level is 1.5 × 105 Pa, determine the pressure at the lower level?
