A shaft is supported on two 3-recess hydrostatic journal bearings which are symmetrically placed with respect to a radial load W. The shaft rotates at an angular speed of Ns rps. For a capillary compensated bearing, the supply pressure is 2.0 × 106 N/m². The shaft diameter is 6.0 cm. The bearing length L is 6.0 cm. The width of the axial land is 0.1L and angular extent of circumferential land is 200. The operating eccentricity ratio is 0.4. Calculate the optimum radial clearance for minimum power consumption for a shaft speed of 500 rpm. Determine the recess pressures, load capacity, and oil flow rate. The viscosity of the oil is 0.05 Pas and oil density is 900 Kg/m³.
