Question 633: Thermodynamics & KTG

Question

The relation between efficiency $(\eta)$ of Carnot engine and coefficient of performance $\left(\eta_1\right)$ of refrigerator is

Accepted Answer

$$ \begin{aligned} & \eta=1-\frac{T_2}{T_1} \ & \eta_1=\frac{T_2}{T_1-T_2}=\frac{\frac{T_2}{T_1}}{\frac{T_1}{T_1}-\frac{T_2}{T_1}}=\frac{1-\eta}{1-(1-\eta)}=\frac{1}{\eta}-1 \ 	herefore \quad & \frac{1}{\eta}=\eta_1+1 \ 	herefore \quad & \eta=\frac{1}{\eta_1+1} \end{aligned} $$

Answer

$\eta=\frac{1}{1+\eta_1}$

Answer

$\eta=\frac{1}{1-\eta_1}$

Answer

$\quad \eta=\frac{\eta_1}{1-\eta_1}$

Answer

$\eta=\frac{1+\eta_1}{\eta_1}$
