Cubic feet per minute to Litres per second conversion

How to convert cubic feet per minute to litres per second?

Cubic feet per minute (cfm) is a common unit of measurement used to indicate the volume of air (or any gas) moved per minute. To convert cfm to liters per second (L/s), you need to know the conversion factors:

1 cubic foot = 28.3168 liters 1 minute = 60 seconds

The conversion formula from cfm to L/s is:

$\text{L/s} = \text{cfm} \times \frac{28.3168 \text{ L}}{1 \text{ cubic foot}} \times \frac{1 \text{ minute}}{60 \text{ seconds}}$

Now let's apply this to convert 1 cfm to L/s:

$\text{L/s} = 1 \times \frac{28.3168}{60}$

$\text{L/s} = 0.4719467$

So, 1 cfm is approximately 0.472 L/s.

Real World Examples for Other Quantities of Cubic Feet per Minute

1. Household Exhaust Fan:

   • A typical bathroom exhaust fan might have a rating of 70 cfm.
     • Conversion to L/s: $70 \times 0.472 \approx 33 \text{ L/s}$

2. HVAC System:

   • A central air conditioning system could be rated around 400 cfm per ton of cooling.
     • Conversion to L/s: $400 \times 0.472 \approx 189 \text{ L/s}$

3. Industrial Air Compressor:

   • An industrial air compressor might have a flow rate of 1000 cfm.
     • Conversion to L/s: $1000 \times 0.472 \approx 472 \text{ L/s}$

4. Automotive Engine Air Intake:

   • A high-performance car engine might have an air intake rate of 300 cfm.
     • Conversion to L/s: $300 \times 0.472 \approx 142 \text{ L/s}$

5. Commercial Kitchen Ventilation:

   • A commercial kitchen hood might require 1500 cfm.
     • Conversion to L/s: $1500 \times 0.472 \approx 708 \text{ L/s}$

These examples illustrate how varying amounts of cfm can be converted to liters per second, providing a better understanding of airflow in different contexts.
