The Pressure distribution, the load carrying capacity and the flow rate of externally pressurized gas bearings can be assessed by means of an electric analogy by electrolytic tank. In this paper, the elements of externally pressurized journal bearings with multiple gas supply holes arranged circumferentially in one, two, three and four rows are analized by electrolytic tank analogy, and the flow rate efficiency η_Q and the load carrying capacity efficiencyη_L are determined. The load carrying capacity of journal gas bearings is calculated by a simplified theory, and the optimum size of flow restrictors and the minimum gas pumping power are given. The above results should be correct so far as the flow is controlled by the viscosity of the gas as usually is for gas bearings, and a method for optimum design is derived. The experimental results will be described in the 2nd report.
