ENGRI 1290 4 m out m in Conceptual component of a thermal power plant v in z in z out Q W v out Let’s take any power component of a power plant. We notice that 1- this component exchanges heat or work with the outside 2- fluid goes in 3- fluid comes out The component will be represented by a box with rigid walls and filled by a fluid. The fluid going in has a mass m in The fluid coming out has a mass m out The velocity going in is v in The velocity coming out is v out The input height is z in The output height is z out This box exchanges heat (fission reaction,…) and work (shaft,…) with the outside. In Out

ENGRI 1290 5 m in m out z out v out Energy entering in the box v in z in The energy of the fluid entering the box is: 1-The internal energy U in gained from heat or work exchanges from the previous power component; 2-kinetic energy 2 in in mv /2 ; 3-potential energy in in mgz; 4-compressional work to push m in inside in in FL . L in A in , the input area The force F in is the force required to compress the volume of fluid … F in =p in A in So we get  2
