On a Generalized Mass-Velocity Relation for Disk Galaxies and Galaxy
  Clusters
  We consolidate the BFJ and BTF (MVD) relations into a generalized Scaling
Mass Velocity Relation applicable to both pressure-supported galaxy clusters
and rotation-supported galaxies. Unlike MOND inspired relations containing a
characteristic acceleration scale and its normalization factor, our proposal is
dependent on observed dynamic surface mass densities and discrepancies. We
perform the same analysis for a sample of HIFLUGCS galaxy clusters (Tian et al,
2021) found in prior work with SPARC galaxies (arXiv: 2101.01537). For this
galaxy cluster sample, we find little evidence for a universal acceleration
constant as previously recognized for galaxies. We finish with an examination
of the virial energies for the combined sample recovering a mass-energy
relation consistent with the phenomenology.
