Mit Offenheit und … In fluid mechanics (especially fluid thermodynamics), the Grashof number (Gr, after Franz Grashof ) is a dimensionless number which approximates the ratio of the buoyancy to viscous forces acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number (Re).

WebThe first German settlers came to America in 1608, in Jamestown, Virginia. Many more sailed over in 1680 and settled down in areas of New York and Pennsylvania. The largest number of Germans may have migrated to America between 1840 and 1900. Many of those immigrating to America in the early years were in search of religious and political freedom.
