Why carnot cycle are consider as ideal reversible cycle?
carnot cycle is the highiest efficiency
If compression ratio is samethen whose efficiency will be greater diesel cycle or otto cycle?
Diese
Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
Why is the Krebs cycle used?
Because of it's [cyclic] efficiency.
A term to describe the efficiency of the metabolism and the recovery cycle?
Metabolic rate.
Which has highest air standard efficiency carnot cycle or sterling cycle?
Theoretically, both cycles have the same efficiency: 1-Tc/Th, where Tc is the temperature at which heat is dissipated and Th is the temperature at which heat is added.
What is the efficiency of a transformer?
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
Why efficiency of rankine cycle is more in winter than in summer?
there is more heat loss..
How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
What is the advantage of rankine reheat cycle?
Among other advantages, this pervents the vapor from condensing during its expansion which can seriusly damage he turbine blades, and improves he efficiency of the cycle, as more of the heat flow into the cycle occurs at higher temperature.
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.
Is it better to leave your air conditioning running all the time - or to switch it on and off as necessary?
Your air conditioner should have a built in thermostat and cycle as necessary. The air conditioner takes a little while to reach peak efficiency. Once the room is cooled it will cycle on and off as necessary. If you manually cycle the air conditioner, you are greatly reducing its efficiency.
