A 120° central partial bearing is 2 in. in diameter and 3 in. long, r/c = 1000; n = 900 rpm. SAE 10 oil is used. Bearing is self-cooled with C1 = 2 Btu/hr/ft2/°F and C2 = 8. Room temperature is 100°F. Assume the housing surface temperature rises one-half as much as the average film temperature.
(a) Plot the curve for average film temperature versus P.
(b) Plot the curve for ho versus P.
Use a temperature range from 145°F to 170°F inclusive at 5° intervals.
