In what ways can you increase the efficiency of a heat engine?
Therefore, the efficiency of the heat engine can be increased by decreasing the temperature of the cold sink or increasing the temperature of the hot source.
How can Carnot efficiency be increased?
The efficiency of the carnot engine can be increased by either increasing the sink temperature or by decreasing the reservoir temperature.
On what factors the efficiency of Carnot engine depends?
The efficiency of a Carnot engine depends solely on the temperatures of the hot and cold reservoirs.
What is the efficiency of Carnot engine?
The efficiency of carnot’s engine is 50\%.
What would make an engine more efficient?
The greater the expansion ratio, the more efficient the engine, in principle, and higher compression / expansion -ratio conventional engines in principle need gasoline with higher octane value, though this simplistic analysis is complicated by the difference between actual and geometric compression ratios.
How do you increase the efficiency of a Carnot engine?
Carnot engine efficiency can be increased by decreasing the sink tempereture . Because as we know that work can be produced by heat engine till, both sink and source do not acquire the same temperature ( condition of equillibrium) . As soon as both acquire the same temperature the work production stops and the work produced or we get is maximum.
What is the advantage of lowering the sink temperature in Carnot engine?
So, lowering the sink temperature is generally preferred in most cases. Carnot engine efficiency can be increased by decreasing the sink tempereture . Because as we know that work can be produced by heat engine till, both sink and source do not acquire the same temperature ( condition of equillibrium) .
What is the Carnot cycle and Carnot theorem?
In this section, we will learn about the Carnot cycle and Carnot Theorem in detail. Any system working between two given temperatures T 1 (hot reservoir) and T 2 (cold reservoir), can never have an efficiency more than the Carnot engine working between the same reservoirs, respectively.
What is the difference between T1 and T2?
Since T2 is always greater than T1 we came to the conclusion that partial differentiation of efficiency with respect to T1 is always greater than partial differentiation with respect to T2. So, the more effective way to increase the efficiency is to decrease T1 i.e. sink temperature.
