Abstract: The Konigl inhomogeneous jet model can successfully reproduce 
most observational features of jets in active galactic nuclei (AGN), such as
 the flat spectrum characteristic of AGNs, core emission and size, when 
suitable physical parameters are adopted. The proper motion of the jet 
component sets a constraint on the jet kinematics. We improve the calculation 
on the radiative processes in the jet given by Konigl(1981), which is no longer 
valid for the jet with a small viewing angle. Based on the inhomogeneous jet 
model, we calculate the minimal kinetic luminosity of the jet required to reproduce
 the measured proper motion of jet component, core size and emission by 
very-long-baseline interferometry (VLBI). Using this approach, we calculate 
the minimal kinetic luminosity of the jets for a small sample of flat-spectrum 
radio AGNs. Our results show that the minimal kinetic luminosity is comparable 
with the bolometric luminosity for most sources in the sample. For most sources, 
we find the minimal jet kinetic luminosity can be higher than the bolometric 
luminosity. The physical implication of the results are discussed in the work.
