Pune University Mechanical Engineering 3rd Semester question paper

Applied Thermodynamics

Section I
Unit I

1. (a) Write a note on reversibility. [4]

(b) Prove that Kelvin-Planck statement and Clausius statement are
equivalent.

(c) At steady state, a refrigerator cycle removes 18,000 kJ/h of
energy by heat transfer from a space maintained at –40ºC
and discharges energy by heat transfer to the surroundings
at 20ºC. If the actual COP of the cycle is 25% of that of
the theoretical cycle operating between thermal reservoirs of
these two temperatures, determine power input to the cycle
in kW.

2. (a) Write a note on ‘Principle of Increase of Entropy’. [4]

(b) State and prove ‘Clausius Inequality’. [8]

(c) Two kg of air is heated at constant pressure of 200 kPa
to 500ºC. Calculate entropy change if the initial volume
is 0.8 m3.

UNIT II

3. (a) Derive an expression for available energy of non-flow
system. [6]

(b) Sketch the following processes on P-V and T-S planes :
(i) Reversible adiabatic
(ii) Isothermal.

(c) 0.25 kg of air at a pressure of 140 kN/m2 occupies 0.15 m3
and from this condition is compressed to 1.4 MN/m2 according
to 1.25 PV = C. Determine :
(i) Change in internal energy of air
(ii) Work done and
(iii) Heat transfer.
