In general, efficiency is the ratio between the output of a device and the input, . For thermal efficiency, the input, , to the device is heat, or the heat-content of a fuel that is consumed. The desired output is mechanical work, , or heat, , or possibly both.
From the first law of thermodynamics, the energy output can't exceed the input, so

How do you increase thermal efficiency in converting heat energy to mechanical energy eg in internal combustion engine or gas turbine is there any device to improve thermal efficiency?
To increase thermal efficiency in converting heat energy to mechanical energy in internal combustion engines or gas turbines, you can improve combustion efficiency, reduce heat losses, and optimize engine design. There are devices like turbochargers, intercoolers, and regenerators that can help improve thermal efficiency by recovering waste heat and increasing engine performance. Additionally, advanced technologies like variable valve timing, direct fuel injection, and hybrid systems can further enhance efficiency.
How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
What gas is used in thermal windows?
The gas typically used in thermal windows is argon. Argon is an inert, non-toxic gas that is denser than air, helping to reduce heat transfer and improve the energy efficiency of the window.
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.
What are the effects of humidity on gas turbine performance?
an increase in relative humidity will increase the Gas turbine output. and thermal efficiency. when the ambient tempeature is high at that time also if RH is high it will have a slight positive impact on GT output & Efficiency.
How many liters of gas to drive one hundred kilometer?
Depends on the efficiency of the engine.
What are the effect of temperature fluctuation on gas turbine?
If you are referring to a gas engine then the temperature affects the efficiency of the engine. The colder it is, the less efficient. The hotter it is the more efficient. I hope that this answers your question
Which is faster diesel or gas engine?
Gas is faster but with diesel you have a bigger towing capacity, probably better fuel efficiency, and more horsepower.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
How can you find the efficiency of an AGR nuclear reactor?
The efficiency of an AGR (Advanced Gas-cooled Reactor) nuclear reactor can be calculated by dividing the electrical power output by the thermal power input. Essentially, it represents how much of the thermal energy produced in the reactor is converted into usable electrical power. Typically, the efficiency of AGR reactors ranges from 32% to 38%.
What is thermal coating?
Thermal coatings are highly advanced material systems applied to metallic surfaces, such as gas turbine or aero-engine parts, operating at elevated temperatures.
