Question

в тепловой машине температура нагревателя 600 К температура холодильника на 200 К меньше чем у нагревателя Максимальный возможный КПД машины равен

Answer 1

η = (T1-T2)/T1 * 100% = (600-400)/600 * 100% ≈ 33.(3) %

Answer 2

Calculation of Maximum Possible Efficiency (КПД) in a Heat Engine

To calculate the maximum possible efficiency (КПД) of a heat engine, we can use the Carnot efficiency formula. The Carnot efficiency is the maximum efficiency that a heat engine can achieve when operating between two temperature reservoirs.

The formula for Carnot efficiency is:

Carnot efficiency (КПД) = 1 - (Tc/Th)

Where: - Tc is the temperature of the cold reservoir (in Kelvin) - Th is the temperature of the hot reservoir (in Kelvin)

In this case, the temperature of the heater (nagrevatel) is 600 K, and the temperature of the refrigerator (kholodilnik) is 200 K lower than the heater.

Let's substitute the values into the formula:

Carnot efficiency (КПД) = 1 - (Tc/Th) = 1 - ((600 K - 200 K)/600 K)

Simplifying the equation:

Carnot efficiency (КПД) = 1 - (400 K/600 K) = 1 - (2/3) = 1/3

Therefore, the maximum possible efficiency (КПД) of the heat engine is 1/3 or approximately 33.33%.

Please note that this calculation assumes ideal conditions and does not take into account any losses or inefficiencies in the heat engine. The Carnot efficiency represents the theoretical maximum efficiency that can be achieved by a heat engine operating between two temperature reservoirs.
