Alpacas are raised for their soft and luxurious fleece (sometimes called fiber). Each shearing produces roughly five to ten pounds of fleece per animal, per year. This fleece, often compared to cashmere, can be turned into a wide array of products from yarn and apparel to tapestries and blankets.
1 gallon of propane is about 90,000 BTU/hour. A 20 lb tank holds a little more than 4 gallons. My patio propane fireplace is 60,000 BTU. At full blast, a 20 lb tank will last about 6-7 hours, which is really close to the calculation. 32 people found this useful.
