a) [1 Water flows into a 2 story apartment through a 5.08 cm diameter pipe and the water meter registers a 46 psi gauge pressure at the ground level. The pipes taper down to 2.54 cm in diameter at the 2nd floor, 6.8 m above ground. If the water flows at 2.2 m/s at the 2nd level, what is the gauge pressure in psi at the 2nd level?
