g) What is mean free path?
h) Explain the concept of equipartition of energy?
i) Define compressibility factor.
j) What is adiabatic flame temperature?
2. From TdS equation derive Cp-Cv = tVβ2/K.
3. The gas neon has a molecular weight of 20.183 and its critical temperature, pressure and volume are 44.5 K, 2.73 Mpa and 0.0416 m3 / kg mol. Reading from acompressibility chart for a reduced pressure of 2 and a reduced temperature of 1.3, the compresssibility factor Z is 0.7. what are the corresponding specific volume, pressure, temperature and reduced volume?
4. Derive an expression for availability function for a flow system exchanging heat with two heat reservoirs.
5. What is Gibb’s theorem? Show that in a defusion process at constant temperature the entropy increases and the Gibbs function decreases.
6. (a) Define fugacity and activity?
(b) Explain thermomechanical exergy and chemical exergy.
7. What is the maximum work output possible from a reversible heat engine working between the two finite reservoirs of heat capacity M1C1 and M2 C2 respectively. The initial temperature of the thermal reservoirs are T1 and T2 respectively.
