1L means 1000ml
1000ml to be given for 8hours
For 1hr(60mins Or 3600sec), (1000/8 ) ml to be given ie 125ml.
For 1min, 125/60 ml to be given
If 1ml contains 18drops.
So 125/60 ml contains {(125/60) ×18}drops or 37.5drops.
So 37.5 drops to be given for 1 min or drip rate is 37.5drops/min or roughly 38drops/min.
