A Carnot engine is operated as an air conditioner to cool a house in the summer. The air conditioner removes 14 kJ of heat per second from the house and maintains the inside temperature at 293 K, while the outside temperature is 369 K.

The power required for the air conditioner under these operating conditions, in SI units, is closest to:

Answer :

In SI units, the needed power for the air conditioner under these operating circumstances is most closely 69.3 kW.

The power required for a Carnot engine operating as an air conditioner is given by the formula

[tex]P = \frac{Q_H}{\eta },[/tex]

where [tex]Q_H[/tex] is the rate of heat removed from the house, and η is the Carnot efficiency. The Carnot efficiency is given by the formula,

[tex]\eta =\frac{ 1 - T_C}{T_H}[/tex]

where [tex]T_C[/tex] is the cold reservoir temperature (293 K) and [tex]T_H[/tex]is the hot reservoir temperature (369 K).

Thus, the power required for the air conditioner is given by:

[tex]P = \frac{14 kJ/s }{(\frac{1 - 293 K}{369 K}) }\\=\frac{ 14 kJ/s }{ (1 - 0.798) }\\[/tex]

[tex]= \frac{14 kJ/s }{ 0.202 }\\P= 69.3 kW.[/tex]

Therefore, the power required for the air conditioner under these operating conditions, in SI units, is closest to 69.3 kW.
