What is Rankine Cycle? | Technology-Articles.com

What is Rankine Cycle? Rankine cycle is a theoritical cycle which converts heat energy into work. Developed by William John Macquorn Rankine in the 19th century, it has been widely used to steam engines. Currently, the rankine cycle is used in power plants and produces 90% of the world's electricity.
