Water flows at speed of 6 m/s through a horizontal pipe of
diameter 3.5 cm. The gauge pressure P1 of the water in the pipe is
1.7 atm. A short segment of the pipe is constricted to a smaller
diameter of 2.4 cm .
What is the gauge pressure of the water flowing through the
constricted segment? Atmospheric pressure is 1.013 × 10^5 Pa. The
density of water is 1000 kg/m^3 . The viscosity of water is
negligible. Answer in...

Water is delivered to a 4.0 cm diameter fountain head from a 6.9 cm diameter pipe that is 3.4 m below the fountain head and at a pressure of 94 kPa. The fountain head shoots the water straight up into the air. Neglect all losses. a.) What is the velocity of water coming out of the fountain head? Hint: Must use Bernoulli AND Continuity b.) What is the volume flow rate of the water through the fountain head? Hint: Q=vA

Water is flowing through a 10-cm diameter water pipe at a rate
of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is
bolted to the pipe in order to slow down water that exits into the
atmosphere, as shown. Disregarding frictional effects, determine
the force exerted on the flange due to the water flow. Density of
water = 1,000 kg/m^3.
