    1. The problem statement, all variables and given/known data
    As we all know , energy will lose from high to low. in the equation , the energy at A ( Pa +za +](Va)^2 ]/2g ) is higher , while the energy at B is lower. So, why the water flow from B to A ? why not A to B ?
    20.39 +10.52-hf = 32.98
    2. Relevant equations
