A water pipe having a 2.6 cm inside diameter carries water into the basement of a house at a speed of 0.90 m/s and a pressure of 240 kPa. If the pipe tapers to 1.6 cm and rises to the second floor 7.5 m above the input point, what are the (a) speed and (b) water pressure at the second floor? I tried to set it up as: But clearly it's wrong because I didn't take into consideration the area (given the diameter) etc. I would appreciate any help. Thank you.
