## Homework Statement

An inventor claims to have developed a device with the following properties:

net work output per cycle = 20,000 J

heat output per cycle = 50,000 J

high temperature = 450 C

low temperature = 160 C

Calculate the heat input per cycle.

## Homework Equations

ΔE

_{TH}= W + Q

efficiency max = 1 - (Tc/Th)

## The Attempt at a Solution

I tried taking efficiency max, which I got 0.40111, and dividing the heat output by that to get 124,654 J. I'm not sure if that's what I'm supposed to be doing, still confused on this.
