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
