Energy per unit weight

  1. Jan 24, 2016 #1
    1. The problem statement, all variables and given/known data
    why the author said the equation 3-4 as energy per unit weight ?
    as gamma = rho g , gamma has the unit of kg(m^-3)(ms^-2) = kg(m^-2)(s^-2) , gamma is clearly not weight ...

    2. Relevant equations


    3. The attempt at a solution

    You'll have to supply some additional information about this equation 3-4, which is not included in your attachment.

    The quantity γ = ρ ⋅ g is known as the weight density of the fluid, however.

    Work out the units on both sides of the equation.
