Externally pressurized gas bearing — shallow pocket (design chart)
Dimensionless pressure ratio, load, stiffness and load-change (at ε=0.5) design formula for an externally pressurized gas bearing with a shallow-pocket (constant-flow) restrictor.
Pressure ratio, β₀0.701259371332999
Dimensionless load, F* (ε=0)0.8006296856664995
Dimensionless stiffness, S* (ε=0.5)0.1705204173751358
