| Popis: | A new empirical equation for liquid heat capacity calculation, as a function of temperature and pressure is recommended. This four-parameter equation was tested and compared to the four-parameter equation developed by Guseinov et al. (1988), five-parameter equation developed by Garg et al. (1993) and nine-parameter equation developed by Nakagawa et al. (1993), using 73 sets with 4395 literature experimental heat capacity data for 46 chemical compounds. The obtained results indicate that the proposed four-parameter equation gives in many cases better results than the tested four- and five-parameter equations and in few cases even better than the nine-parameter equation. |
