For infinitely-long-frozen-seal fans

Want to understand infinitely long frozen seals?  A fairly good place to start is the classic study:

ANALYSIS AND DESIGN OF THE FROZEN SEAL,” J.F. Bailey, Oak Ridge National Laboratory, February 12, 1957. The report explains that: “As a result of a theoretical analysis of an infinitely long frozen seal, an equation has been derived for relating the power required to drive the seal, the viscosity of the liquid being sealed, the shaft speed, and the dimensions of the seal.”
