Calculation of flow rateTotal amount of solution x Drop factorTime (hours x minute)= Drops / minutee.g. A doctor has prescribe to give 3000ml in 24hrs with a giving set drop factor of 20drops/min
3000 x 20 drops24 x 60 min= 42 drops / minuteNoteEvery giving set has a drop factor calculated from the factory and is labeled on the pack.
