Water flows at speed of 5.2 m/s through a
horizontal pipe of diameter 3.1 cm . Suppose
a thick pipe is connected to a thinner pipe.
In the first pipe the gauge pressure P1 of the
water is 1.9 atm . The diameter of the smaller
section is 2 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^3
. The viscosity of water
is negligible.
Answer in units of atm.
