Answer 1

This lets us calculate how fast it is being administered. Typically every 10 drops is 1 ml of fluid. We call that a macro drip. We also have micro drip sets that vary with some being 20 or even 60 drops to 1 ml. Those can be used for more concentrated medications but nowadays we would typically just use a pump that is more accurate for those medications.
