Kugwiritsa Ntchito Rankine Cycle mu Steam Power Plants Steam Power Plants (PLTU) ndi imodzi mwa njira zopangira magetsi zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Zimagwira ntchito pogwiritsa ntchito mphamvu yotentha kuti zisinthe madzi kukhala nthunzi yothamanga kwambiri komanso yotentha kwambiri. Mphamvu ya nthunzi iyi imasinthidwa kukhala mphamvu yamakina kudzera mu turbine, yomwe kenako imasinthidwa kukhala mphamvu yamagetsi... Werengani zambiri

Kusanthula kwa Entropy mu Uinjiniya Njira za Thermodynamic Mu uinjiniya, thermodynamics ndi maziko ofunikira kwambiri pakumvetsetsa momwe mphamvu imayendera ndikusintha mkati mwa makina—kuchokera ku injini zoyatsira mkati ndi ma turbine a nthunzi kupita ku ma compressor ndi makina oziziritsira.
