First time Poster Need help with some math problems

[The WaterGuy]

Im trying to get into the field of water treatment
ive taken a bunch of courses and studied my *** off but every time the math kicks my ***.


I need help finding out how to solve problems for:
Polymers % and lbs

polymer, lbs = (water, lbs)
---------------------------- i dont know it which is why its hard to do anything for practice because i cant find it anywhere



Polymer, % (Polymer, lbs x 100%)
----------------------------
(Polymer, lbs + Water, lbs)


Feed rate, mL/min = (gpd)(3785 mL/gal)
----------------------------
(1440 min/d)
or




Number of mL/min = (Number of gallons used)(3785 mL/gal)
-----------------------------------------------------
(1440 min/d)


Chemical Feed, lb/d = (Flow, mgd)(Dosage, mg/L)(8.34lbs/gal)



Chemical Feed, lb/d = (Flow, mgd)(Dosage, mg/L)(8.34lbs/gal)
-----------------------------------------------------
(percent purity / 100%)
When not 100% pure






i dont even know where to begin


and sadly i could use some help with simple conversations like seconds => minutes => hours => days =>

I have absolutely no idea what question you are asking! Please post again without the "pretty" formatting.

We can help you with the math, but you'll need to explain whatever industry-specific whatsits to which you're making reference.

Are you maybe referring to converting between (or cancelling) units?
