The drop has been standardized in the metric system to equal exactly 0.05 milliliters.
So 20 ml = 400 drops in 60 minutes = 62/3 drops per minute = 9 seconds between drops.
(150 ml / 1 hour) x (10 drops / ml) x (1 hour / 60 minutes) = (150 x 10 / 60) (ml - drop - hour / hour - ml - minute) = (1,500 / 60) = 25 drops / minute
1000x20/720 = 28 gtts/min
~60 drops solution: 20 drops/mL * 3 mL = 60 drops

Answer about 13 gallons depending on your assumptions of how many drops per gallon.Several methods to figure this out:1 million drops of water is 1666.667 fluid oz. There are 600 drops per fluid oz and 1,000,000 divided by 600 is 1666.667(last digit is rounded)1666.667 oz if about 13 U.S. gallons or if you prefer metric it is49.289 litersMethod 290840 Drops in 1 Gallon ( but that value depends on water temp and other factors)90840 Drops/1 gallon=1,000,000 drops/x gallons90840x=1,000,000x=11.0084 gallonsSo this method gives 11 gallons and if we want to know how many cubic inches that we note that:1 gallon of water is 231 cubic inches. So 11.0084x231=2542 cubic inches.______I found another professor give this example:http://jwilson.coe.uga.edu/emt668/EMAT6680.Folders/Howard/Million.Drops.of.Water/Million.Drops.of.Water.html10 drops of water = 1 milliliter and: 10,000 drops = 1 Liter then: 1,000,000 drops = 100 Liters and my reference quoted that: 1 Gallon = 3.5 Liters, so 1,000,000 drops of water = 28.5714 gallonsMethod 3The example above 10 drops per ml, and of course you can easily imagine that the size of a drop of water will not be uniform. It depends on temperature and the dropper and many other factors.Most people use 15-20 gtts( drops) per ml, usually 20.So the slightly larger value in this result comes from the fact that the drops are much bigger, 10 per ml instead of 20. Divide 28.574 by 2 and the you have 14.2 gallons. Also 1 US gallon = 3.78541178 liters so using 3.5 is a low estimate.So here is the same calculation as above using different assumptions. The example below uses 3.785 liters per gallon and 20 drops per ml.20 drops of water= 1 milliliter20,000 drops = 1 liter1 gallon is 3.785 liters.so(20,000 drops/1 liter)(3.785 liter/1 gallon)=75,700 drops/gallon(compare this to 90840 used in the first part above)75,700 drops/gallon=1,000,000 drops/X gallons.Solve for x75,700X=1,000,000and the answer is 100, 000 drops is 13.21 gallons
If the set delivers 10 drops per ml, you want a total of 1000x10 drops of normal saline over 4 hours. This is 10000 drops and now divide that by 4 hours, but you will want the 4 hours as minutes. So 4 hours is 240 minutes. Then answer must be in the form drops per minute so divide 10000 drops by 240 minutes and the exact answer is 125/3 which is 41.67 drops per minute. We need can't measure part of a drop so round this off to 42 drops per minute. Now let's check the answer. 42 drops per minute x240 minutes=10000 drops which is 1000 ml. DONE
60ml x 15 drops/ml = 900 total drops 900 total drops divided by 60 minutes (1 hour) = 15 drops per minute
1400 mL x 15 drops per mL = 21000 total drops "per day" assumes 24 hours. 24 hours x 60 minutes per hour = 1440 minutes in one day 21000 total drops divided by 1440 minutes = 14.58 drops per minute (round up to 15 drops per minute)

If 600ml of liquid is released at 20ml per 40 minutes it will be completely gone in 20 hours. 600/20 = 30 drops 30 drops * 40 minutes = 1200 minutes 1200/60 = 20 hours
(150 ml / 1 hour) x (10 drops / ml) x (1 hour / 60 minutes) = (150 x 10 / 60) (ml - drop - hour / hour - ml - minute) = (1,500 / 60) = 25 drops / minute
Volume to be infused x drop factor Time of infusion x Minutes = Drops/ minute
( 50 mL x 60 drops / mL ) / 30 drops/min = 100 minutes
For an IV rate of 100 ml per hour, you would set the IV pump to deliver 1.67 ml per minute (100 ml divided by 60 minutes). If you are using a standard IV administration set with a drip factor of 10 drops per ml, this would equal 16.7 drops per minute (1.67 ml multiplied by 10 drops). You would typically round this to the nearest whole number, so in this case, it would be 17 drops per minute.
Converting minutes to weeks is easy. Just multiply by 60 minutes per hour x 24 hours per day x 7 days per week to get 10080 minutes per week. The drops per gallon is a little harder to figure. I assume you are talking water, still, it could vary depending upon the purity and temperature of the water. However, U.S. Geological Survey says that they have made a number of measurements, and figure an average of 15140 drops per gallon. Take your 2 1/2 gallons. Multiply by 15140 to get to drops per week. Divide by 10080 to get to drops per minute. The answer is: around 3.75 drops per minute.
50*10 = 500 drops.
(42 drop/minute) x (60 minute/hour) = 2,520 drop/hour
