Homework Help: Mass of one component in two component w/feed flowrate

  1. Sep 29, 2015 #1
    1. The problem statement, all variables and given/known data
    Basically I'm given a feed flowrate - 70,000 gal/day
    I know the weight percent is 35% and the component is Triethylene Glycol - density - 1.255g/ml

    2. Relevant equations

    3. The attempt at a solution
    So i did this

    70,000 gal/day * .35 * (.0378mL/1gal)* 1.255g/mL = g of Triethylene Glycol

    Is this correct, i know the gal->mL might be wrong but is the basic setup correct using wt%?

    You soft of have the right idea. But, "gal->mL might be wrong" is a gross understatement. Do you really think that 1/30 of a ml is the same as one gallon (1 gallon is close to 4 liters)? And the units of your answer are incorrect. What happened to "day."

    Thanks! yeah, i knew it wasnt right the gal->mL i was just short on time and yeah i left off days, because i was going to convert it later to hours since im comparing it to some charts for a lab report
