A 2 ½ ×2 ½ - in sleeve bearing uses grade 20 lubricant. The axial-groove sump has a steady-state temperature of 110◦F. The shaft journal has a diameter of 2.500 in with a unilateral tolerance of −0.001 in. The bushing bore has a diameter of 2.504 in with a unilateral tolerance of 0.001 in. The journal speed is 1120 rev/min and the radial load is 1200 lbf. Estimate
(a) The magnitude and location of the minimum oil-film thickness.
(b) The eccentricity.
(c) The coefficient of friction.
(d) The power loss rate.
(e) Both the total and side oil-flow rates.
(f) The maximum oil-film pressure and its angular location.
(g) The terminating position of the oil film.
(h) The average temperature of the side flow.
(i) The oil temperature at the terminating position of the oil film.
