Learning Objectives & Experiments

The SR3028 unit is designed for comprehensive experimentation and training in the principles of heat conduction through fluids. It enables practical studies of both steady-state and transient thermal transfer mechanisms.

✔️ Steady Heat Conduction in Liquids and Gases

·        Determine the thermal resistance of various fluids

·        Measure thermal conductivity (k) at multiple temperatures

·        Compare heat conduction behavior in water, oil, air, and CO₂

✔️ Transient Heat Conduction

·        Interpret transient thermal states during heating and cooling cycles

·        Understand dynamic response using the block capacity model
