A water pipe tapers down from an initial radius of R1
= 0.2 m to a final radius of R2 = 0.09 m. The water
flows at a velocity v1 = 0.86 m/s in the larger section
of pipe.
1. What is the volume flow rate of the water?
2. What is the velocity of the water in the smaller section?
3. Using this water supply, how long would it take to fill up a
swimming pool with a volume of V = 130 m3? (give your
answer in minutes)
4. The water pressure in the center of the larger section of the
pipe is P1 = 243120 Pa. Assume the density of water is
103 kg/m3. What is the pressure in the center
of the smaller section of the pipe?
5. If the pipe was turned vertical and the volume flow rate in the
larger section is kept the same, which answers would
change?
*the speed of water in the smaller section
*the volume flow rate in the smaller section
*the pressure in the smaller section
