1. What is Syringe Pump Flow Rate?

The syringe pump flow rate is the volume of fluid delivered per unit time by a syringe pump, calculated based on the syringe dimensions and the linear speed of the plunger.

2. How Does the Calculator Work?

The calculator uses the syringe pump flow equation:

Where:

• \( Q \) — Flow rate (mL/min)
• \( D \) — Syringe diameter (mm)
• \( L \) — Linear speed of plunger (mm/min)
• \( T \) — Time (min)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The equation calculates the volume displaced by the plunger movement per unit time, accounting for the cross-sectional area of the syringe.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation is essential for precise drug delivery, laboratory experiments, and industrial processes where controlled fluid dispensing is required.

4. Using the Calculator

Tips: Enter syringe diameter in mm, linear speed in mm/min, and time in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical flow rate range for syringe pumps?
A: Most syringe pumps operate in the range of 0.001 mL/min to 100 mL/min, depending on syringe size and motor precision.

Q2: How does syringe diameter affect flow rate?
A: Flow rate increases with the square of the diameter - doubling the diameter quadruples the flow rate at the same linear speed.

Q3: What's the relationship between flow rate and linear speed?
A: Flow rate is directly proportional to linear speed - doubling the speed doubles the flow rate for the same syringe.

Q4: Why is time included in the calculation?
A: The equation can calculate either flow rate (when time is known) or total volume delivered over a specific time period.

Q5: Can this be used for different fluid types?
A: The calculation is valid for any Newtonian fluid, though viscous fluids may require higher pump pressures.
