The following data is given for a 360° hydrodynamic bearing:
Radial load = 3.2 kN
Journal speed = 1490 rpm
Journal diameter = 50 mm
Bearing length = 50 mm
Bearing diameter = 50.1 mm
Viscosity of lubricant = 25 centipoise
The dimensionless Sommerfield number for the bearing is
_____________.
    Correct answer is '0.12'. Can you explain this answer?

    Unit bearing pressure, p = W/Ld = 3.2x1000/50 x 50 = 1.28 N/mm2
    Radial clearance, c = (D - d)/2 = (50.1- 50)/2 = 0.05 mm
    = (25/0.05)2(25/109)(1490/60)(1/1.28)
    = 0.121
