Why do we need energy efficiency experts? Introducing them means hitting the energy monopolist over the head.

So what this says is the efficiency of any reversible engine T1 has to be one minus T2 over T1.

这就是说,任何可逆热机的效率都是,负T2除以。

The efficiency for the one on the left q1 is minus w over q1, The efficiency prime for the one on the right is minus w prime over q1 prime.

左边的效率是,负w除以，右边的效率是,负w一撇除以q1一撇。

q1 So we saw that efficiency is one plus q2 over q1.

效率等于1加q2除以。
