A reheater cycle with two stages of reheating is executed with steam expanding initially from 20.544 Mpa and 540oC. The pressures of two reheaters are 3.2544 Mpa and 0.85544 Mpa, and the steam leaves each reheater at 540 oC. Condensation occurs at 70 oC. Calculate W, ec and ee.

Atomic diffusion in solids

In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.
