Homework Help: Total energy of the flowing fluid

  1. Jan 15, 2016 #1
    1. The problem statement, all variables and given/known data
    Since this scanned notes is not clear enough , so I retype some parts of the notes,

    The enthalphy , h is given by the formula , h = u +Pv = u + P/ ρ


    I wanna ask about the total energy of the flowing fluid , which is given by the formula =

    P/ ρ + e = h + ke +pe = h + (V^2) /2 +gz

    Why the h appear in the equation , if h appear in the equation , then shoudn’t the equation = u + P/ ρ + e ???

    Why in the first part of the equation of total energy of the flowing fluid , the u is missing ?

    2. Relevant equations


    3. The attempt at a solution
