To get WORK out of an engine do you want the heat flowing from the HOT temperature source Q(hot) to be LARGER or SMALLER than the heat flowing into the COLD temperature source?
Please be clear!
Homework Answers
For work flow output from the
thermodynamic cycle, heat flow from hot temperature must be greater
than heat flow into cold temperature.
