Several studies provide different relations between the physical parameters of active region (AR) coronal loops, such as temperature, density, loop length and magnetic field. These relations predict particular scaling laws that can be compared with observations. In quiet-Sun loops, this task is specially difficult since they are not identifiable in observations. To this end, tomographic reconstructions of the coronal electron density and temperature can be combined with potential-field source-surface (PFSS) models of the coronal magnetic field. Here we study Carrington rotation 2082, during the solar activity minimum between Solar Cycles 23 and 24. By tracing the tomographic results along the magnetic field lines of the model the electron density and temperature, as well as energy-related quantities, are computed for each closed magnetic field line. We analyze the relation between observed and inferred parameters of quiet-Sun coronal loops to determine scaling laws.
