How do you calculate fluid flow rate?
Summary. Flow rate Q is defined to be the volume V flowing past a point in time t, or Q=Vt where V is volume and t is time. The SI unit of volume is m3. Flow rate and velocity are related by Q=A¯v where A is the cross-sectional area of the flow and v is its average velocity.

How do you calculate fluid intake and output?
Subtract the volume in the graduate from the total volume of fluid served to the client. For example, if the volume left in the graduate is 80 mL, this is subtracted from the full serving amount of 700 mL, giving us a total fluid intake of 620 mL (Fig.
How to calculate IV flow rate?
To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
