Unsteady heat transfer

WebIn the unsteady state condition, the temperature becomes a function of both position and time. Analysis of temperature variations with time during the unsteady state period is … WebAn unsteady state heat transfer lab report is a report that documents the results of an experiment that investigates how heat is transferred in a system where the temperature changes over time. This type of heat transfer, also known as transient heat transfer, is different from steady state heat transfer, where the temperature remains constant.
