1. Attitude Angle vs S. Note C is half of diamtetrical clearance

2. h_min/C vs S. Trajectory (based on hmin and angle) shown in lower left hand corner

3. Variables h_min = dimension of smallest film thickness
Phi = angle where h_min occurs – see figure
S = (R/C)^2 * mu*n/P
R = shaft radius
C = radial clearance (half of diametral clearance)
mu = kinematic viscosity
n = shaft rotation rate in revolutions per time
P = force / projected area = F / (2*R*L)
Beta = arc of bearing. Suggest to use 180 for plain journal bearing with distribution grooves near splitline
