ABSTRACT
A 1.3 cm (1/2 in)-diameter brass rod was cooled from 100°C to 30°C, with incremental temperature and time readings taken. A mathematical model was developed to predict the transient rod temperature versus time. The model predictions of temperature versus cooling time were compared with the experimental values of rod temperature versus cooling time. The averaged error for the 17 temperatures for which times were recorded was 10%; however, the time required to cool the rod from 100°C to 30°C was 391 s experimentally, versus 400 s from the model results, an error of only a 2.3%.
