英语翻译
请翻译下面一段话,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.

Answer 1

一个单一泡沫分配喷嘴被增加在房间的中心天花板水平并且连接到 CAF 系统,由一个商业的注射者所组成以计量器计量泡沫浓缩语进水水流和一个解决- 空气注入之内而且混合室.(图 3) 在它到达了喷嘴之前 ,CAF 穿越是 "用力擦洗"9.8 尺 (3 公尺) 的 1 寸- 直径 (25.4 毫米-直径) 钢管.对于所有的测试,系统流动 0.3个百分比班级的一分钟 (每一分钟 24 公升)6.3 加仑泡沫解决和一分钟 (一分钟 200 公升)52.8 加仑的空气,以 9.5:1 的扩充率产生泡沫.
火测试装备
初步行动实验 heptane 溢出的 1 加仑 (4-公升) 产生了池火 30 秒大约持续的直径 4.9 尺 (1.5 公尺) .为了要评估 CAF 系统,燃料溢出每个模拟了 1 加仑 (4 公升) 三个容器把持,为总数为 3 加仑.(12 公升) e 池被藉由以 1 加仑的比率每一分钟 (每一分钟 4 公升) 流动 heptane 进测试房间和 1 分钟之后点燃池产生.地板布满对确定是寸 (25 毫米) 深的水 0.9 燃料被适当地分配.这用大约 2.2 3 分钟大约持续的 MW 的热释放率产生火
