Liquid Problem with Bernoulli's Equation

  1. Jun 15, 2006 #1
    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.

    Oh, but to solve this problem you'll need to use your last topic equation (the continuity equation :wink: )

    All righty...

    if it's A1V1 = A2V2...do we take into consideration the final height?
