Your boil rate is the amount of water that you evaporate off in a given amount of time. If you have 40 gallons of sap you will need to evaporate off 39 gallons of water. At 10 gph it would take 3.9 hours. If you ran that 2% through an RO to 6% you will have 13.3 gallons of concentrate and will need 1.3 hours to boil to syrup. (numbers are just for an example, you actually need 43.5 gallons at 2%)
