Question Paper
What is a Thermodynamic system Explain its types.
Explain intensive and extensive properties with examples.
Explain Bourdon pressure gauge with a neat sketch.
Explain Zeroth law of Thermodynamics.
Explain Absolute temperature scale.
A temperature scale of a certain thermometer is given by t a in P where and are constants and is the thermometric property of the fluid in the thermometer. If the ice point and steam point thermometric properties are found to be 1·5 and 7·5 respectively, what would be the temperature corresponding to the thermometric property of 3·5 on Celsius scale?
What is heat? Give sign convention. How is it related to work?
Explain Joule's experiment to prove I-law of thermodynamics f3W =f3Q.
Derive the equations for Clausius inequality.
What is entropy? Explain.
What is reversibility and irreversibility Explain.
Prove that change of entropy for unit mass is given by,
Discuss available and unavailable energy.
State and explain the two statements of II-law of thermodynamics.
Discuss various refrigerants.
Discuss the following terms
Ton of refrigeration
COP

Explain Reversed Brayton Cycle.
An air compressor has a volumetric efficiency of 70% when tested, the discharge state being 5 bar, 150°C and inlet state is 1 bar 15°C. If the clearance is predict the new nvol, when the discharge pressure is increased to 700 kPa. Assume that the ratio of real to ideal T1vol of the exponent remains constant.
10.(a) Derive the expression for work input of a single stage reciprocating air compressor.
