A liquid (? = 1.65 g/cm3) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm2, the flow speed is 262 cm/s, and the pressure is 1.20 105 Pa. In the second section, the cross-sectional area is 3.50 cm2.
Calculate the smaller section's pressure.
