Water flows at speed of 5.5 m/s through a horizontal pipe of diameter 3.2 cm . Suppose a thick pipe is connected to a thinner pipe. In the first pipe the gauge pressure P1 of the water is 1.8 atm . The diameter of the smaller section is 2.3 cm . P1 5.5 m/s 3.2 cm 1.8 atm P2 v2 2.3 cm Please find the gauge pressure of the water flowing through the smaller pipe Atmospheric pressure is 1.013 × 10^5 Pa . The density of water is 1000 kg/m3 . The viscosity of water is negligible. Answer in units of atm.
