Homework Help: Fluid Mechanics: pump configuration

  1. Oct 23, 2012 #1
    1. The problem statement, all variables and given/known data

    Develop the pump head curve.

    2. Relevant equations


    3. The attempt at a solution

    Top branch: ## \Delta h=2(a-b(\frac{Q}{2})^2) ##
    Bot branch: ## \Delta h=a-b(\frac{Q}{2})^2 ##

    Combining them is where I'm having trouble; I don't understand what to do with the a term. Add? Multiply? Average? In a simpler parallel-pump configuration, with single pumps on each branch, the a term of the pump curve is unchanged; but in this configuration the a terms are different.
