Hardy Cross method correction problem

  1. May 22, 2016 #1
    1. The problem statement, all variables and given/known data
    I have problem with the flow rate (Q) in junction that join 2 loops together , where k = 4 ,

    Why in the second correction , the corrected Q in first and second loop = 21 clcockwise for left loop , and for 21 anticlockiwise for right loop ?



    2. Relevant equations


    3. The attempt at a solution
    IMO, it should be 10+2 = 12 for the left loop , and for the right loop , it should be -10-9= -19 , am I right ??????
