Difference between Carnot and ideal cycle?
What is the difference between ideal and actual cycle?
When was Rankine Generating Station created?
Rankine Generating Station was created in 1905.
Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.

Difference between rankine and brayton cycle?
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
What is the difference between the Carnot cycle and the Rankine Cycle?
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat
What are the Assumptions of air standard cycles?
The air standard cycle assumes that the process can be modeled as a closed flow system (Rankine cycle boiler or air conditioner), even for an open flow ( gas powered internal combustion motor, turbine, or turbo jet). The only other assumption that is commonly made in entry level thermodynamics courses is that the air mixture inside of the the device can be modeled as an ideal gas. Any further assumptions would be based off the devices used in the cycle, such as nozzles, turbines and well you get the picture. Also note that because you are using an ideal gas for an air standard cycle, you can use all assumptions of a cold air standard, where heat capacities are assumed to be constant.
What is the significance of the Rankine cycle in thermodynamics and how does its PV diagram illustrate the energy conversion process within a power plant?
The Rankine cycle is important in thermodynamics because it is a theoretical model that represents the ideal process for converting heat into mechanical work in a power plant. The PV diagram of the Rankine cycle shows the stages of this energy conversion process, including heat input, expansion, heat rejection, and compression. By analyzing the PV diagram, engineers can optimize the efficiency of power plants by understanding how energy is transferred and transformed throughout the cycle.
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What is rankin cycle?
The Rankine cycle is the fundamental thermodynamic underpinning of the Steam_engine. It is named after William_John_Macquorn_Rankine
What are the relative advantage of Rankine Cycle over Carnot Cycle in thermal power plants?
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
What are the Assumptions of air-standard cycles?
The air standard cycle assumes that the process can be modeled as a closed flow system (Rankine cycle boiler or air conditioner), even for an open flow ( gas powered internal combustion motor, turbine, or turbo jet).

Difference between Carnot and ideal cycle?
What is the difference between ideal and actual cycle?
What is modified rankine cycle?
modified rankine cycle basically same as rankine cycle but main difference is inisentropic expansion process.we are nt expanding the styeam completely.steam is expanded up to certain level and after that it dumped in condenser due to high vacuum in condenser.the work losses by restricting the expansion of steam is very less which can be neglected.so that the stroke length of cylinder is reduced and the capitalcost of engine also reduced.engine performance is also good
What is air-standard cycle?
An air-standard cycle is a theoretical cycle used to analyze the performance of internal combustion engines. It assumes ideal conditions where air is the working fluid and the combustion process is ideal without any heat losses. This simplification helps in understanding the basic thermodynamic principles governing engine operation.
