If you have 1000 ml's or medication to be infused at 12ml/hour, and the set is calibrated at 10 drops per mL:

Question

What is the drip rate?

Answer 1

12mL/hr * 10drops/mL = 120 drops/hr

120drops/hr * 1hr/60min = 2 drops/min

And, based on the 1000mL,

1000mL * 1hr/12mL = 83.3 hours

So, 2 drops per minute for 83.3 hours.

Answer 2

2 drops per minute is correct.

Answer 3

I think it's two drops a minute.

!0 drops per mL then 12mL is 120 drops which is per hour and  to find out what it is per minute divide by 60 which is 2.
