14. A liquid (p = 1.35 g/cm3) flows through two horizontal sections of tubing joined end to end. In the first section, the cross-sectional area is 10.0 cm2, the flow speed is 275 cm/s, and the pressure is 1.20 X 10^5 Pa. In the second section, the cross-sectional area is 2.50 cm2. Calculate flow speed and pressure in the smaller section.
