Title Velocity calculation for local exhaust inlets - empirical design equations, graphical design concepts
Bibliographic information Dec. 1983, Vol.44, No.12, p.937-947. Illus. 17 ref.
Abstract In the 1st part, updated equations are proposed for calculating centerline velocities of local exhaust inlets, and the effects of inlet factors including flanging, width-to-length ratio and face velocity are discussed. The 2nd part describes graphical design concepts useful for approximating airflow characteristics of local exhaust inlets. They include free-hand sketching, vector addition, imaginary inlets, conformal mapping, area/velocity change and the use of computer graphics.
