The doctor writes a prescription for na heparin 20,000 units in 500 ml n. s. infuse over 8 hours. what is the flow rate in ml/hr?

I think this type of equation could be conducted in simple division equation since it does not involve drop rate.

we know that there is 500 ml of substance and should be infused within 8 hours period.

So the flow rate in ml/hr would be:

500/8 = 62.5 ml/hr
