A water pipe tapers down from an initial radius of R1 = 0.23 m to a final radius of R2 = 0.08 m. The water flows at a velocity v1 = 0.83 m/s in the larger section of pipe.

Using this water supply, how long would it take to fill up a swimming pool with a volume of V = 153 m3? (give your answer in minutes)

4)

The water pressure in the center of the larger section of the pipe is P1 = 263380 Pa. Assume the density of water is 103 kg/m3.

What is the pressure in the center of the smaller section of the pipe?

Water is flowing into a factory in a horizontal pipe with a radius of 0.0163 m at ground level. This pipe is then connected to another horizontal pipe with a radius of 0.0380 m on a floor of the factory that is 11.6 m higher. The connection is made with a vertical section of pipe and an expansion joint. Determine the volume flow rate that will keep the pressure in the two horizontal pipes the same. _________ m3/s
