Rankine cycle is a thermodynamic cycle used in power plants to convert heat into mechanical work.

• Rankine cycle is a thermodynamic cycle that converts heat into mechanical work.

• It is commonly used in power plants to generate electricity.

• The cycle consists of four main components: a boiler, turbine, condenser, and pump.

• Steam is generated in the boiler by heating water using a fuel source.

• The steam then enters the turbine where it expands, producing mechanical work.

• After exiting...read more

There are four main types of coal: anthracite, bituminous, sub-bituminous, and lignite, each with distinct properties and uses.

• Anthracite: Highest carbon content, used for heating and metallurgical processes.

• Bituminous: Most abundant, used for electricity generation and steel production.

• Sub-bituminous: Lower carbon content, primarily used for electricity generation.

• Lignite: Lowest rank, used mainly in electricity generation and as a fertilizer.

A thermodynamic cycle is a series of processes that involve the transfer of heat and work to and from a system.

• A thermodynamic cycle consists of a series of processes such as compression, heating, expansion, and cooling.

• The cycle returns the working substance to its original state after completing a full cycle.

• Examples of thermodynamic cycles include the Carnot cycle, Rankine cycle, and Brayton cycle.
