Answer 1

ANSWER.

* Calculation of drops per minute.

    Formula

      Drops per minute (gtt/min) = Volume(ml) /Time(min) * Drop factor(gtt/ml).

Here

    Volume(ml) = 100 ml (100cc)

     Time(min) = 480 min (8 hrs)

     Drop factor = 60 gtt/ml.

As per above formula

       Drops per min = 100/480 * 60

                               = 0.208 * 60

                               = 12.48

                               = 12.5 gtt/min.
