Water flows at speed of 5 m/s through a horizontal pipe of diameter 3.4 cm. The gauge pressure P1 of the water in the pipe is 1.5 atm. A short segment of the pipe is constricted to a smaller diameter of 2.3 cm. What is the gauge pressure of the water flowing through the constricted segment? Atmospheric pressure is 1.013 × 105 Pa . The density of water is 1000 kg/m3 . The viscosity of water is negligible. Answer in units of atm.
