The efficiency of the Carnot engine is increased by decreasing the lower temperature and increasing the higher temperature but more effects on the efficiency of the Carnot cycle is by decreasing lower temperatures as compared to an increase in higher temperature.

## Which is the more effective way to increase the efficiency of a Carnot engine to increase T1 and keeping T2 constant or to decrease T2 keeping T1 constant?

Reduction in T2 is more effective than equal increase in T1. Therefore, reduction in temperature of the sink is a better proposition than increase of source temperature by the same amount. Carnot efficiency increases with increasing source temperature or/and decreasing sink temperature.

## What would be the most effective way to 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.

## Is there any way to increase the efficiency of a Carnot heat engine other than by increasing th or decreasing TL?

Is there anyway to increase the efficiency of a carnot heat engine other than increasing Th or decreasing Tl? energy cannot be created or destroyed. … The entropy of the working fluid of the ideal Carnot cycle (increases, decreases, remains the same) during the isothermal heat rejection process.

## How do you increase the thermal efficiency of a Carnot heat engine How about for actual heat engines?

As the difference in temperatures of the hot and cold reservoir increases, the efficiency of a Carnot engine increases.

## How can we increase the efficiency of a heat engine can we get 100% efficiency if yes how?

The equation is Hot Temperature minus Cold Temperature over Hot Temperature. These temperatures must be in kelvins to work in the equation. Hence the only way to get 100% efficiency is to have an engine run in an absolute zero vacuum, which we dont have the technology to produce, assuming its possible at all.

## Why Carnot cycle is the most efficient?

According to the Carnot theorem, the reversible engine will always have a greater efficiency than the irreversible one. … The Carnot cycle achieves maximum efficiency because all the heat is added to the working fluid at the maximum temperature.

## 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 explain the possible way of measuring the efficiency of a heat engine?

The maximum theoretical efficiency of a heat engine (which no engine ever attains) is equal to the temperature difference between the hot and cold ends divided by the temperature at the hot end, each expressed in absolute temperature.

## Can the efficiency of an engine always be improved by increasing the thermal energy put into the system during a cycle?

It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term.

## What is the efficiency of Carnot engine?

The efficiency of carnot’s engine is 50%.

## 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 should be the temperature of the source to increase the efficiency to 30%?

An ideal heat engine exhausting heat at 77∘C is to have a 30% efficiency.

## How do you find the thermal efficiency of a Carnot cycle?

The ideal Rankine cycle efficiency (or Carnot cycle efficiency) can be defined as (T2-T1)/T2. T2 is defined as the absolute temperature of the heat source and T1 is the absolute temperature of the heat sink.
