1. INTRODUCTION An engine is a device which transforms one form of energy into another form. Most of the engines convert thermal engine to mechanical work and therefore they are called heat engine. Heat engine can be broadly classified into two types. i. Internal combustion engine ii. External combustion engine 1.1 CLASSIFICATION OF INTERNAL COMBUSTION ENGINE:- This type of engine is again classified into two types. i. Rotary ii. Reciprocating The reciprocating engine is a highly complex

INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous

Heat Conduction Experiment 5: Free and Forced Convection Experiment 6: Thermal Radiation Experiment 1: Heat Capacity of Gases 1. BACKGROUND The first law of thermodynamics can be illustrated particularly well with an ideal gas. This law describes the relationship between the change in internal intrinsic energy ΔUi the heat exchanged with the surroundings ΔQ and the constant-pressure change pdV. dQ = dUi + pdV

CHAPTER 4 THERMODYNAMICAL‚ THERMOPHYSICAL‚ AND RHEOLOGICAL PROPERTIES OF FRUITS AND FRUIT PRODUCTS 4.1. INTRODUCTION Most processed and many freshly consumed fruits receive some type of heating or cooling during handling or manufacturing. Design and operation of processes involving heat transfer needs special attention due to heat sensitivity of fruits. Both theoretical and empirical relationships used when designing‚ or operating‚ heat processes need knowledge of the thermal properties
