Can The Efficiency Of A Heat Engine Be Greater Than 1? Efficiency of a heat engine can’t be greater than efficiency of Carnot’s engine. Why is it not possible to have an efficiency greater than 1? It is not possible to have an efficiency of greater than 1 or an efficiency percentage greater than 100%.
Why Is Otto Cycle Less Efficient Than Carnot Cycle? The Otto cycle is more complicated than a Carnot cycle, in a number of ways: … This makes the engine less efficient that a Carnot engine, because heat is being discharged at a temperature that is not as cool as the environment. What is the most
Why 100 Efficiency Is Impossible? 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. Can you ever have 100% energy efficiency? Generally, energy
Why 100 Efficient Engine Is Not Possible? 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. Why can’t we have 100 efficiency? Explanation:
What Is A Reversed Heat Engine? The reverse heat engine is a device that transfers energy from an object at a lower temperature to an object at a higher temperature by doing work on the system. … Refrigerators are reverse heat engines that pump energy out of the inside of the fridge and into the
Why Is Carnot Cycle Important? The Carnot cycle has the greatest efficiency possible of an engine (although other cycles have the same efficiency) based on the assumption of the absence of incidental wasteful processes such as friction, and the assumption of no conduction of heat between different parts of the engine at different temperatures. Why
Why Is Carnot Cycle Impractical? Carnot cycles are not encountered in reality since achieving isothermal heat transfer is very difficult (needs very large heat exchangers and long time). Also process 3-4 requires a pump or compressor that can handle two phase mixture (liquid and vapor) which is impractical. Why is Carnot cycle not possible? In
Why Is Carnot Engine Most Efficient? The Carnot cycle Why is Carnot efficiency maximum? The most efficient heat engine cycle is the Carnot cycle, consisting of two isothermal processes and two adiabatic processes. … This means that the Carnot cycle is an idealization, since no real engine processes are reversible and all real physical processes
Why Is Carnot Engine Impossible? The Carnot cycle Is a Carnot engine possible? Any engine using the Carnot cycle, which uses only reversible processes (adiabatic and isothermal), is known as a Carnot engine. Any engine that uses the Carnot cycle enjoys the maximum theoretical efficiency. … Carnot cycles without heat loss may be possible at
How Can You Increase The Efficiency Of A Machine? For a lever, you can increase the machine’s efficiency by reducing the friction. What makes a machine efficient? The efficiency of a machine concerns how much energy is lost to friction and heat during its operation. Since work is the change in kinetic energy, the efficiency
