The objective is to determine the basics understanding of following concepts: Law of Conservation of Mass Law of Conservation of Energy Co-relation between Mass and Energy Co-relation between Energy and Work Concept about Total Energy First Law of Thermodynamics Law of Conservation of Mass This law states that mass is non destructible or it can … Read more

Enthalpy, Entropy, And The Second Law of Thermodynamics

The objective is to develop the basics understanding of the following concepts: Internal Energy and First Law of Thermodynamics The cyclic and arbitrary process of a system Reversibility and Irreversibility Entropy and Enthalpy Second Law of Thermodynamics Internal Energy and First Law of Thermodynamics When the energy of a molecule within a system is associated … Read more

Carnot Cycle and Reversed Carnot Cycle

Carnot Cycle The Carnot cycle is a thermodynamic cycle that is known for the best possible efficiency. Carnot cycle changes the energy available in the form of heat to produce useful reversible-adiabatic (isotropic) and other processes. Carnot engine efficiency is one minus the ratio of the temperature of the hot thermal reservoir to the temperature … Read more

Rankine Cycle

Ideal Rankine Cycle Principles of thermodynamics are useful for power cycle for of electrical power generation (i.e net power output) and to study refrigeration & heat pump which requires input of net power. Classification of thermodynamics power cycles can be done into two types: Vapor cycle working fluid exists in liquid phase during one part … Read more

Ideal Verses Actual Rankine Cycle

Rankine Cycle is a known mechanical cycle which is being commonly used in the power plants for converting the pressure energy of steam into mechanical energy using steam turbines. Major components of it are rotating steam turbine and boiler pump and stationary condenser and boiler. Boiler is used for heating the water for generation of … Read more

Rankine Cycle and Regenerative Feed Heating

Rankine Cycle From the T-s diagram of Rankine cycle it is evident that at the state 2-2’ working fluid enters the boiler and this temperature is very low temperature at which water is entering the boiler. As a result of its efficiency of the cycle is lower. Regeneration There is a way to overcome this … Read more

Rankine Cycle for Closed Feed Water Heaters and Rankine Cycle Cogeneration

Rankine Cycle with Closed Feed Water Heaters Rankine cycle with closed feed water heaters are having its benefits and is most commonly used in all modern power plants. Closed feed water heater employs indirect mode of heat transfer, i.e extracted steam or bleed steam from the turbine transfers its heat indirectly to feed water in … Read more

Rankine Cycle Efficiency Improvement Techniques

Steam power plants are still the backbone of the total power generation in the Asia pacific. Thus even a small improvement in the form of increasing the efficiency has a tremendous effect on the fuel saving and also reduction in emission of green house gases. Thus one should not miss out any opportunity to find … Read more
