Litres per minute to Cubic feet per minute conversion

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

To convert from litres per minute (L/min) to cubic feet per minute (CFM), you need to use the relationship between litres and cubic feet. Here’s the step-by-step process:

1. Understand the basic conversion: 1 cubic meter (m³) is equal to 1000 litres (L) and also equal to approximately 35.3147 cubic feet (ft³).

2. Set up the conversion factor: 1 litre = 0.001 cubic meters 1 cubic meter = 35.3147 cubic feet

   Therefore, 1 litre = 0.001 m³ × 35.3147 ft³/m³ ≈ 0.0353147 ft³

3. Convert 1 L/min to CFM: $1 \text{ L/min} \times \frac{0.0353147 \text{ ft³}}{1 \text{ L}} \approx 0.0353147 \text{ CFM}$

So, 1 L/min is approximately 0.0353 CFM.

Real-World Examples for Other Quantities:

1. 5 Litres per minute (L/min): $5 \text{ L/min} \times 0.0353147 \text{ CFM/L} = 0.1765735 \text{ CFM}$ Therefore, 5 L/min is approximately 0.177 CFM.

2. 20 Litres per minute (L/min): $20 \text{ L/min} \times 0.0353147 \text{ CFM/L} = 0.706294 \text{ CFM}$ Therefore, 20 L/min is approximately 0.706 CFM.

3. 50 Litres per minute (L/min): $50 \text{ L/min} \times 0.0353147 \text{ CFM/L} = 1.765735 \text{ CFM}$ Therefore, 50 L/min is approximately 1.766 CFM.

Real-World Applications:

1. Aquarium Aeration: An aquarium's air pump operates at 5 L/min, which is approximately 0.177 CFM. This flow rate is sufficient for aquariums that require moderate levels of aeration.

2. Residential HVAC System: A small duct can have a flow rate of 50 L/min (approximately 1.766 CFM). This rate is suitable for providing ventilation to a specific room or area.

3. Portable Oxygen Concentrators: Concentrators typically deliver oxygen at rates from 1 to 5 L/min (0.0353 to 0.177 CFM), depending on the patient's needs.

4. Water Filters and Dispensers: A domestic water filter might purify water at a rate of about 20 L/min (approximately 0.706 CFM), providing a steady supply of clean water for a household.

Understanding these conversions and real-world applications helps illustrate how different flow rates in litres per minute translate into cubic feet per minute in various contexts.
