A pipe tapers out from an initial area A1 = 6.6x10-2 m2 to a final area A2 that is nine times as large over a distance d = 0.4 m. Water enters from the left in a steady volumetric flow of 300 liters/second and initial gauge pressure 17 kPa .
1. Find the area at distance 0.272 m into the flare.
2. Find the speed of the water flow at distance 0.272 into the flare.
3. By how much does the pressure in the water change between the x = 0.272 m point and the initial value?
