How much efficient is geothermal energy?
It is usually not energy that is efficient or inefficient. Rather, the technology used to extract it may be efficient or inefficient. In the case of any heat energy, the upper limit to the efficiency is given by the Carnot equation for heat engines, and depends on the temperature of the heat source, as well as the environmental temperature.
Why do engines get discolored?
engines get discolored because of the heat . the heat comes from combustion from gass and air
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
Does heat engines use heat to do work?
by engine
Does car works on heat produced by petrol when it is burnt?
Yes. Gasoline and diesel engines are both heat engines.
Heat engines use heat to do work?
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
What is the best indication that the transfer of electrical energy to the lamp is inefficient?
A high amount of energy lost as heat is a clear indicator that the transfer of electrical energy to the lamp is inefficient. This can typically be observed by feeling the lamp and the surrounding area for excess heat.
How are heat engines classified?
heat engines are classified on the location of the combustion chamber , if it is outside the whole set up then it is external heat engine and vice versa.
Is a engine in a car the same as a heat engine?
A car engine is a heat engine, but there are various types of heat engines outside the realm of car and truck engines.
Are refrigerators and air conditioners examples of heat engines?
No, refrigerators and air conditioners are not examples of heat engines. Heat engines typically convert heat into mechanical work, while refrigerators and air conditioners transfer heat from one location to another using a refrigeration cycle.
What is the difference between internal combustion engine and heat engine?
An internal combustion engine is a type of heat engine that generates mechanical energy by burning fuel inside the engine. A heat engine, on the other hand, is a broader category of engines that convert heat energy into mechanical work through various processes, including combustion, thermodynamic cycles, and heat transfer. In essence, all internal combustion engines are heat engines, but not all heat engines are internal combustion engines.
How much of the energy in petrol do petrol?
Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.
