The video simply explains the Rankine Cycle in Thermodynamics. Rankine Cycle is one of the cycles in Thermodynamics that contributes a big impact on our society by providing electricity in the Industries and in our Residence.

Rankine Cycle in Thermodynamics is also one of the major subjects in the Engineering courses or curriculum and this video teaches you the basic things about this cycle. Rankine Cycle is a fun thing to study.

Rankine Cycle was named after a Scottish polymath and Glasgow University Professor, William John Macquorn Rankine
It is a Vapor Power Cycle
Power Cycle is a cycle that uses heat to generate work and since it’s a vapor cycle, it uses the vapor phase or in this case steam to rotate the blades of the turbine.
It actually utilizes the heat energy contained in coal, oil, or natural gas and then converts it into mechanical energy and eventually electrical energy. Which of course provides electricity in our city and in our homes.
One of the best definitions for this cycle is that it Closely describes the process of Steam Turbine Systems and is Derived from the Carnot Cycle. The most efficient thermodynamic cycle tells us that power is dependent on the temperature difference between a heat source and a cold source, which is our surroundings. The higher the difference, the more mechanical power can be efficiently extracted out of heat energy.


So now let’s talk about the variants or the Types of Rankine Cycle.
We have a REHEAT RANKINE CYCLE, it is a cycle which we introduced the exhausted steam back into the boiler to reheat it)
We also have a REGENERATIVE RANKINE CYCLE, we bled a part of the steam into heat exchangers to preheat the feed water before entering the boiler)
There is also an ORGANIC RANKINE CYCLE, which uses an organic high molecular mass fluid with a boiling point occurring at a lower temperature than the water-steam phase change.
A SUPERCRITICAL RANKINE CYCLE is also one of the types, Water is the working fluid and it is operated at above its critical pressure.



So those are the types of Rankine Cycle, but here in this video, we will only discuss the most basic and fundamental of this cycle, the IDEAL RANKINE CYCLE.
We must be aware that this operates slightly different than the REAL RANKINE CYCLE
This is a REVERSIBLE CYCLE, common sources of irreversibilities are neglected such as frictional pressure drops and undesired heat transfer with the surroundings.

Constant pressure or isobaric process and constant entropy or isentropic process is used for the equipment involved in this cycle.
The working fluid is WATER, it will undergo a closed-loop and will be reused constantly



So by the way Why do we use WATER as the working fluid?
Well, simply because it is NOT TOXIC, NOT REACTIVE, HIGHLY ABUNDANT, LOW COST, and GOOD THERMODYNAMIC PROPERTIES.



To make a Rankine cycle, we need 4 processes (Process 1-2 for the Boiler, Process 2-3 for the Turbine, Process 3-4 for Condenser, and finally process 4-1 for the Pump).

Watch the video of Rankine Cycle to learn this cycle in a simple and fun way.
