The flow rate in mL/hr is 10.
An infusion may be defined as a process of being extracted some compounds from original products.
The flow rate is calculated as:
Amount of dose given to patient per hour = 20mg/hr.
Total concentration of dose = 500mg.
Total volume in mL = 250mL.
Flow rate = Amount of dose given to patient per hour/Total concentration of dose × Total volume in mL.
= [tex]\frac{20 mg/hr}{500 mg} * 250[/tex] = 10mL/hr.
Therefore, The flow rate in mL/hr is 10.
