Introduction
In engineering, chemistry, and various scientific fields, unit conversions are essential for accurate measurements and calculations. One such conversion involves transforming a volumetric flow rate from cubic millimeters per minute (mm³/min) to gallons per second (gal/s). This article provides a detailed, step-by-step guide on converting 32.88 mm³/min to gallons per second, ensuring precision and clarity.
Units
Before performing the conversion, it’s crucial to understand the units involved:
- Cubic Millimeters per Minute (mm³/min): A metric unit measuring the volume of liquid passing a point per minute.
- Gallons per Second (gal/s): An imperial unit measuring the volume of liquid passing a point per second.
Since these units belong to different measurement systems (metric vs. imperial) and different time scales (minutes vs. seconds), a two-step conversion is necessary:
- Volume Conversion: mm³ → gallons
- Time Conversion: minutes → seconds
Step 1: Convert mm³ to Gallons
First, we need to establish the relationship between cubic millimeters and gallons.
- 1 cubic millimeter (mm³) = 2.64172 × 10⁻⁷ gallons (US liquid)
Given the flow rate 32.88 mm³/min, we first convert the volume:32.88 mm3=32.88×2.64172×10−7 gallons32.88mm3=32.88×2.64172×10−7gallons32.88 mm3=8.6859×10−6 gallons32.88mm3=8.6859×10−6gallons
Step 2: Convert Minutes to Seconds
Since the original unit is per minute, we convert it to per second:1 minute=60 seconds1minute=60seconds
Thus, the flow rate in gallons per second is:8.6859×10−6 gallons60 seconds=1.44765×10−7 gallons/second60seconds8.6859×10−6gallons=1.44765×10−7gallons/second
Final Conversion
Therefore, 32.88 mm³/min is equivalent to:1.44765×10−7 gal/s1.44765×10−7gal/s
Verification and Cross-Checking
To ensure accuracy, let’s verify using an alternative approach:
- Convert mm³ to liters:1 mm3=1×10−6 liters1mm3=1×10−6liters32.88 mm3=3.288×10−5 liters32.88mm3=3.288×10−5liters
- Convert liters to gallons:1 liter=0.264172 gallons1liter=0.264172gallons3.288×10−5 liters=8.6859×10−6 gallons3.288×10−5liters=8.6859×10−6gallons
- Convert minutes to seconds:8.6859×10−660=1.44765×10−7 gal/s608.6859×10−6=1.44765×10−7gal/s
The result matches our initial calculation, confirming correctness.
Practical Applications
Understanding this conversion is useful in:
- Microfluidics: Precise fluid control in lab-on-a-chip devices.
- Chemical Engineering: Calculating reagent flow rates in small-scale reactions.
- Medical Devices: Regulating infusion pumps and drug delivery systems.
Conclusion
Converting 32.88 mm³/min to gallons per second yields 1.44765 × 10⁻⁷ gal/s. By breaking the conversion into volume and time components, we ensure accuracy. This process is essential for professionals working across different unit systems.
