请翻译下面一段话，谢谢谢谢了。翻译好了另有加分，不要直接用什么快译软件的。A single foam distribution nozzle was mounted at ceiling level at the center of the room and connected to the CAF system, which consisted of a commercial injector to meter foam concentrate into the water stream and a solution-air injection and mixing chamber (see Figure 3). The CAF was “scrubbed” through 9.8 feet (3 meters) of 1-inch-diameter (25.4-millimeter-diameter) steel pipe before it reached the nozzle. For all the tests, the system flowed 6.3 gallons per minute (24 liters per minute) of 0.3 percent Class A foam solution and 52.8 gallons per minute (200 liters per minute) of air, producing foam at an expansion rate of 9.5:1.
Fire test setup
Preliminary experiments showed that a 1-gallon (4-liter) heptane spill created a pool fire 4.9 feet (1.5 meters) in diameter that lasted approximately 30 seconds. To evaluate the CAF system, the fuel spill simulated three containers holding 1 gallon (4 liters) each, for a total of 3 gallons (12 liters). The e pool was created by flowing heptane into the test room at a rate of 1 gallon per minute (4 liters per minute) and igniting the pool after 1 minute. The floor was covered with water 0.9 inches (25 millimeters) deep to ensure that the fuel was properly distributed. This created a fire with a heat release rate of approximately 2.2 MW that lasted approximately 3 minutes.
