In this paper, the specimens, which are finished by lathing and grinding, are axamined. The results obtained can be summarized as follows : (1) In the case in which the phenomenon of leakage was a radial and sector flow, the experimental values of equivalent gap obtained by assuming the surface roughness as anisotropic were in agreement with the analytical values with deviation about 8 %. (2) The characteristic curves of parameters a and b for the carbon steel listed in the 2nd report can be applied for the materials tested in this experiment., Article}, pages = {1321--1331}, title = {An Investigation of Air-leakage between Contact Surfaces : 3rd Report, On Case in which Cast Iron and Brass were used as Specimen}, volume = {17}, year = {1974} }
