ive been working in sugar milling co. i was asigned to dose the clarified  juice with the anti scalant to prevent evaporator from scaling.the chemical that im appling is in a liquid form. the plant required to dose it at 5 ppm. my problem is that ,how much is 5ppm in mL/min. these are the given data: 4000 tons caned per day, 1 ton cane = 1000 li of juice, density of chemical = 9.8 lbs/gallons. i hope you could give me formula. thanks ;D

You would need to know the density of the juice.

ppm means milligram/kilogram,

So you need 5 milligrams of chemical for every kilogram of juice.

You list the density of the chemical, just not the density of the juice.

Usually when people estimate they use the density of water for both, in that particular case 1 ppm = 1 mg/kg = 1 ml/l
