For a hydrostatic thrust bearing,Thrust load=450kN, shaft speed=730rpm...
Calculation of Flow Requirement for Hydrostatic Thrust Bearing:

Given parameters:
Thrust load (W) = 450 kN
Shaft speed (N) = 730 rpm
Shaft diameter (D) = 450 mm
Recess diameter (d) = 310 mm
Film thickness (h) = 0.15 mm
Viscosity of lubricant (μ) = 160 SUS
Specific gravity (γ) = 0.86

Formula:
Flow requirement (Q) = (πDNWh)/60μγ

Calculation:
Q = (π x 450 x 730 x 0.15 x (450-310))/60 x 160 x 0.86
Q ≈ 38.94 L/min

Therefore, the flow requirement for the hydrostatic thrust bearing is 38.94 L/min.
