Question

Ап=2 кДж, Аз=2,5кДж,КПД=?​

Answer 1

Ответ:

n=Aп/Aз *100%

Объяснение:

n=2000Дж/2500Дж *100%= 80%

ответ: 80%

Answer 2

To calculate the efficiency (КПД) of a system, you need to know the input energy (Ап) and the output energy (Аз) of the system. The formula for efficiency is:

КПД = (Аз / Ап) * 100%

Where: Ап is the input energy (in this case, 2 kJ), Аз is the output energy (in this case, 2.5 kJ), and КПД is the efficiency (to be determined).

Now, let's plug in the values and calculate the efficiency:

КПД = (2.5 kJ / 2 kJ) * 100% КПД = 1.25 * 100% КПД = 125%

The efficiency of the system is 125%. However, it's worth noting that efficiencies above 100% are not physically possible. Efficiency values above 100% typically indicate an error in measurements or calculations. In practical terms, an efficiency of 100% would mean all the input energy was converted to useful output energy, and any value higher than 100% suggests that there may be some issues with the data or calculations.
