Water is circulating through a closed system of pipes in a two floor apartment. On the first floor, the water has a gauge pressure of 3.10 105 Pa and a speed of 2.4 m/s. However, on the second floor, which is 4.2 m higher, the speed of the water is 3.4 m/s. The speeds are different because the pipe diameters are different. What is the gauge pressure of the water on the second floor?
