General Equation:

η = \frac{W}{Q_{H}} = 1 - \frac{Q_{L}}{Q_{H}} < 1

η_{c a r n o t} = 1 - \frac{T_{1}}{T_{3}} > η_{t h}

η_{t h} = \frac{w_{n e t}}{q_{i n}} = 1 - \frac{1}{r^{γ} - 1} = 1 - \frac{T_{1}}{T_{2}}

η_{t h} = \frac{w_{n e t}}{q_{i n}} = 1 - r^{\frac{1 - γ}{γ}}

η_{t h} = \frac{w_{n e t}}{q_{i n}} = f (\frac{T_{4}}{T_{2}}, r)
