325 CFM to 420 CFM. Again, knowing the friction loss is essential to sizing a duct and knowing how many CFM are required to meet the room’s load calculation. Duct Size for 300 – 2000 CFM CFMDuct Size (0.06 Friction Loss)Duct Size ...
1)finite-length round duct有限长圆管 1.The sound field of rotating point force in afinite-length round ductis calculated.在自由空间内的计算结果与理论解进行了对比验证,得到较为理想的结果;另外进行了有限长圆管内旋转点声源辐射声场的数值计算,由此对不同长度圆管的结果进行对比,分析了管道长度对声场分布以...
