Engineering Thermodynamics — Summer 2018

Explain in brief the classical and statistical approach of thermodynamics.

Explain the different thermodynamic systems with neat sketch.

Define enthalpy and show that it is the property of the system in case of ideal gases.

Explain Joule’s experiment with neat sketch and state 1st law of thermodynamics.

Prove the equivalence of Clausius and Kelvin-Plank statement.

State the general SFEE and derive for single inlet and single exit fluid with necessary assumptions for diffuser. Also write the function of diffuser.

Discuss perpetual motion machine of the first and second kind.

State and prove Carnot’s theorem.

Show the equivalence of Clausius and Kelvin-Plank statements of 2nd law of thermodynamics.

Using Maxwell relations derive the Clausius-Clapeyron equation.

Explain “Clausius inequality”

Define available and non-available energy. Derive an expression for availability of a non-flow process.

Discuss Rankine cycle with the help of schematic T-Sand h-Sdiagrams.

Explain Brayton cycle with the help of p-v and T-Sdiagrams.

Explain the construction and working of Junker’s gas calorimeter with neat sketch.

Derive an expression for the thermal efficiency of the dual cycle.

What is the difference between Otto cycle and Diesel cycle? Explain why the higher efficiency of the Otto cycle compared to Diesel cycle for the same compression ratio is not a result of practical importance.
