I am new to spraying. I am not doing much this year but was going to test out some different pre-emergents..

I have bought the generic surflan (Oryzalin) pre-emergent..
i was told from an amount per acre.. is there like a formula to use or any ideas of the amount to use per 30 or 50 gallons?
In the past doing my own yard i have used pendelum and have used around 3 pints per 30 gallons.
i use about 2.25 pints of round up per 30 gallons, 1.75 pints of (surfking) per 30 gallons, and about a .5 pints per 30 gallons of the blue color...
But not sure how to mix the pre-emerge.. any tips would be appreciated.

This is a completely unanswerable question. First of all, your spraying apparatus has to be calibrated. You HAVE to know how much your are spraying per thousand.
