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.
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.
How do you higher the thermal efficiency of a cycle?
To increase the thermal efficiency of a cycle, you can: increase the temperature at which heat is added, decrease the temperature at which heat is rejected, and reduce internal irreversibilities and losses in the system. This can be achieved by optimizing the design, improving insulation, and using more efficient components.
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 formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)

Working of 210 mw thermal power station?
Thermal power station of 210mw will work on principle of modified Rankine cycle
What will be the effect to the thermal efficiency to a simple Rankine cycle when the turbine work output decrease?
The efficiency will decrease.Remeber the formula for effiency for a cycle:What we want over what we pay for. So,ηT=WT/QAWhereWT = Work done by the turbineQA = Heat taken from the hot reservoir
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
How does a thermal power station work?
If you are after the thrmodynamic principles, see Wikipedia entry for 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 thermal efficiency of petrol engine?
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
