A horizontal tube consists of a 7.0-cm-diameter pipe that narrows to a 2.0-cm-diameter throat. In the pipe, the water pressure is twice atmospheric pressure and the water flows with a speed of 0.40 m/s. What is the pressure in the throat, assuming that the water behaves like an ideal fluid? The density of water is 1000 kg/m³, and atmospheric pressure is 1.01 × 10⁵ Pa. A) 1.9 atm B) 0.12 atm C) 2.1 atm D) 2.0 atm
