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 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 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 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 four major components of the Rankine cycle?
The four major components of the rankine cycle are as follows: 1. boiler 2. turbine 3. condenser 4. pump i.e. in short (B-T-C-P)
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 the effect of pressure and temrature on the rankine cycle?
In the Rankine cycle, increasing the pressure raises the boiling point of the working fluid, allowing it to absorb more heat during the heating phase and improve the cycle's efficiency. Higher temperatures lead to greater thermal energy conversion into work, enhancing overall efficiency as well. Conversely, lower pressure and temperature can reduce the cycle's efficiency and output power. Thus, optimizing these parameters is crucial for maximizing the performance of a Rankine cycle system.
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.
How do you increase the efficiency of rankine cycle?
To increase the efficiency of a Rankine cycle, you can: increase the boiler pressure to increase the temperature of the steam entering the turbine, lower the condenser pressure to improve the quality of the exhaust steam, and use regenerative feedwater heating to reduce heat losses. Additionally, using superheated steam can also improve the efficiency of the cycle.
Why are you using condenser in rankine cycle?
The condenser is used to lower the temperature of the working fluid. This lowers the pressure and condensates any left over steam, from the turbine, so it will be purely liquid before entering the pump.
Celsius is to Kelvin as Fahrenheit is to what?
Rankine. Rankine is a temperature scale that is used alongside Fahrenheit, where 0 Rankine is absolute zero and each degree Rankine is equal to a degree Fahrenheit.
