摘要
新近出现的扁圆形螺旋风管,对于空间紧凑的交通工具,是一种省地位、省动力、省材料而又加工方便的合理产品。本文提出其以流量为准的当量直径公式,以利于系统计算。
Flat-circular duct, which has appeared in duct design recently, is a reasonable shap for saving energy, metal and mainly, space in a compact ship, Plane or conveyance. In this paper we deduce the circular equivalent of the flat-circular on the basis of equal flow rate and resistance to flow in both ducts.
