This notes should be very easy to follow, especially those who had learnt this but haven't fully grasped the topics. However, this note is also suitable for those who are about to start these topics and want to read ahead. This note will be focused on the vapour power cycle, refrigeration cycle and gas power cycle aspect of the second law of thermodynamics. as well as other skills you need to know in order to answer exam questions of these topics. I believe my note is straight to the point (no...
