Water flows at speed of 4.2 m/s through a horizontal pipe of diameter 3.4 cm. Suppose a thick pipe is connected to a thinner pipe. In the first pipe the gauge pressure P of the water is 1.6 atm. The diameter of the smaller section is 2.2 cm. 1.6 atm P2 V2 4.2 m/s 2.2 cm 3.4 cm Please find the gauge pressure of the water flowing through the smaller pipe Atmospheric pressure is 1.013 105 Pa. The density of water is 1000 kg/m. The viscosity of water is negligible. Answer in units of atm.
