What type of process is the ideal Rankine cycle Mcq?
Ideal ‘Rankine Cycle’ is a __________ process.
Explanation: Ideal Rankine Cycle is a reversible process..
What is the difference between Brayton cycle and Rankine Cycle?
The key difference between Rankine cycle and Brayton cycle is that the Rankine cycle is a vapour cycle, whereas the Brayton cycle is a cycle between liquid and vapour phases. Both the Rankine cycle and Brayton cycle are thermodynamic cycles.
What is ideal process?
Ideal-Process is a web-based, business process automation platform offered in SaaS mode. It allows its users to model their existing processes quickly, design the forms easily, deploy-instantiate-execute the processes seamlessly and analyse the processes ad-hoc.
What is difference between Carnot and Rankine Cycle?
Carnot cycle is a theoretical cycle. Its efficiency at its highest between two temperature difference. Rankine cycle is a practical cycle of turbine and steam engine. Carnot cycle uses air as the working substance.
What are the main components of a Rankine Cycle?
The Rankine Cycle This cycle is composed of four key parts: the generation of high-pressure steam, a turbine, a condenser, and a pump. Steam is generated in the boiler and then transferred to the turbine.
Is Brayton cycle reversible?
The ideal Brayton cycle is made up of four internally reversible processes. The P-v and T-s diagrams of an ideal Brayton cycle are shown on the left. In an ideal Brayton cycle, heat is added to the cycle at a constant pressure process (process 2-3). Heat is rejected at a constant pressure process (process 4 -1).
What are actual cycles?
The actual cycle experienced by internal combustion engines is an open cycle with changing composition, actual cycle efficiency is much lower than the air standard efficiency due to various losses occurring in the actual engine. … Whereas, in actual cycle, burning is completed in a definite interval of time.
What is cycle process?
The process in which the initial and final state is the same is known as a cyclic process. It is a sequence of processes that leave the system in the same state in which it started. … If the cycle goes clockwise, the system does work. If the cycle goes anticlockwise, then the work is done on the system every cycle.
Where is Brayton cycle used?
The Brayton cycle is a thermodynamic cycle used in some heat engines. Notably, it is used for gas turbine engines and some jet engines. The cycle consists of compressing ambient air, mixing the air with fuel, then igniting the mixture, which expands, doing work.
Why pump is used in Rankine Cycle?
The Rankine cycle system consists of a pump, boiler, turbine, and condenser. The pump delivers liquid water to the boiler. The boiler heated by the solar heat converts water to superheated steam. This steam is used to run the turbine which powers the generator.
What is critical point in Rankine Cycle?
The critical point is where the temper- ature and pressure are such that the fluid is no longer classified exclusive- ly as liquid or gas. It is thought of as a fluid above the critical point. The criti- cal point for water is slightly above 3200 psi.
What is a Rankine cycle process?
The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. … The heat is supplied externally to a closed loop, which usually uses water as the working fluid.
What is an ideal cycle?
Ideal cycles are simplified thermodynamic closed cycles to analyze the compression, combustion, and expansion process in an engine with a focus on extraction of work from combustion of the fuel–air mixture.
What four processes make up the simple ideal Rankine cycle check all that apply?
What four processes make up the simple ideal Rankine cycle? The four processes that make up the simple ideal cycle are (1) Isentropic compression in a pump, (2) P = constant heat addition in a boiler, (3) Isentropic expansion in a turbine, and (4) P = constant heat rejection in a condenser.
What is Rankine cycle efficiency?
Thermal Efficiency of Rankine Cycle: The thermal efficiency of the Rankine cycle is the ratio between the work produced by the steam turbine that has been reduced by the pump work, with the incoming heat energy from the boiler. The heat energy from the fuel is transferred to the working fluid i.e. water.
How can we increase the efficiency of Rankine Cycle?
There are three ways to increase the efficiency of the simple ideal Rankine cycle.Decreasing the condenser pressure. The effect of lowering the condenser pressure on the Rankine cycle efficiency is illustrated on a T-s diagram on the left. … Superheating the steam to a high temperature. … Increasing the boiler pressure.
What is the Rankine cycle used for?
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change.
Which is more efficient Rankine or Brayton?
The Brayton cycle (gas turbine) and the Rankine cycle (steam turbine) are two venerable cycles that have served mankind well. However, the combined cycle, which combines the Brayton and Rankine cycles, has resulted in cycle efficiencies exceeding 60% on a lower heating value basis.
