Litres per second to Cubic feet per minute conversion

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

To convert from Litres per second (L/s) to Cubic feet per minute (CFM), follow these steps:

1. Understand the unit conversions:

   • 1 litre = 0.0353147 cubic feet
   • There are 60 seconds in a minute

   Therefore, $1 \text{ L/s} = 1 \text{ litre/second} \times 60 \text{ seconds/minute} \times 0.0353147 \text{ cubic feet/litre}$.

2. Perform the conversion: $1 \text{ L/s} = 1 \times 60 \times 0.0353147 \text{ CFM} = 2.11888 \text{ CFM}$

Hence, 1 L/s is approximately 2.11888 CFM.

Real-World Examples for Different Quantities of Litres per Second

1. Water Flow in Plumbing Systems:

   • A standard shower head typically flows at about 9.5 L/min, which converts to roughly 0.158 L/s.
   • For a higher-flow shower head, let's say with a flow rate of 15 L/min, this converts to 0.25 L/s.
   • Conversion to CFM: $0.158 \text{ L/s} \approx 0.334 CFM$ and $0.25 \text{ L/s} \approx 0.53 CFM$.

2. Airflow in HVAC Systems:

   • A household HVAC system might move air at around 500 CFM. To convert this to L/s: $\text{L/s} = \frac{500 \text{ CFM}}{2.11888} \approx 236 \text{ L/s}$
   • For a smaller office space HVAC system scaled to 200 CFM: $\text{L/s} = \frac{200 \text{ CFM}}{2.11888} \approx 94.36 \text{ L/s}$

3. Agricultural Irrigation Systems:

   • An irrigation system may deliver 50 L/s (large scale agriculture): $50 \text{ L/s} \approx 105.944 \text{ CFM}$
   • For a smaller irrigation system, if it delivers 10 L/s: $10 \text{ L/s} \approx 21.1888 \text{ CFM}$

These examples help illustrate both the calculation process for converting L/s to CFM and how these conversions apply in different real-world contexts.
