Sažetak
The work presents the analytical solution of the non-dimensional entropy generation as a function of non-dimensional temperature in the lumped problem. In the developed model the following non-dimensional variables are included: Biot's number, Bi, Fourier's number Fo and non-dimensional temperature  which is defined as the ratio between absolute temperature of fluid and absolute initial temperature of immersed solid body. The non-dimensional entropy generation has been defined in two ways: by dividing entropy generation with total maximal value of exchanged heat, and with maximal value of entropy generation, respectively. The obtained results are presented in graphical form in the following ranges of non-dimensional variables: 0.0 &pound ; Bi &pound ; 0.1 ; 0 &pound ; Fo &pound ; 20 and 0 &pound ; q &pound ; 2.0.
