Common Applied Thermodynamics Lab Experiments Explained
To appreciate the scope of applied thermodynamics, it helps to explore some of the
classic experiments typically found in lab manuals.
1. Verification of the First Law of Thermodynamics for a Closed System
This experiment is fundamental in illustrating energy conservation. Students measure the
change in internal energy of a system, often a gas contained within a piston-cylinder
assembly, by monitoring heat added and work done. The manual guides them through
using instruments like pressure gauges and thermocouples to collect data and verify that
energy input equals energy output plus the change in internal energy.

Understanding steam and its properties is critical in power engineering. The lab manual
explains how to use steam tables to find enthalpy, entropy, and specific volume at various
conditions. Experiments might involve measuring the pressure and temperature of steam
in a boiler and comparing results with theoretical values from the tables.
3. Performance Analysis of a Heat Engine (Rankine Cycle)
This experiment helps students visualize how heat engines convert heat into work. The
manual outlines procedures to operate a small-scale Rankine cycle setup, measure
temperatures and pressures at different stages, and calculate efficiency. Such hands-on
experience fosters a deeper understanding of practical thermodynamic cycles.
4. Refrigeration Cycle Experiment
Refrigeration is a vital application of applied thermodynamics. The manual provides
instructions for examining the vapor compression cycle, including measuring refrigerant
pressures and temperatures at various points. Students learn to compute the coefficient
of performance (COP), an important metric in refrigeration systems.
