energy systems modeling uids and components can be found in the literature. Analysis of a uid feed system can cover the ow distribution, the functioning of components, or a combination of both. Most of the useful equations for uid analysis are derived from the law of conservation of energy, the principle of continuity, and Newton's second law [13].

uid dynamics is Navier-Stokes equations consist of conservation of momentum, conservation of mass and conservation of energy. Assume the system of dam is in isothermal state, then we can neglect the calculation of uid's thermal energy. The momentum equation has been written as follows: ˆ @u @t + ˆ(uru) = r p+ r2v + ˆg (1) with …

The steam pressures, required for the process, are 22 to 25 Kg/cm 2, for the back pressure turbines, that drive the cane mill (and the electric power generators, also); 0.4 to 2.5 Kg/cm 2, for heat requirements, through the process. Low pressure steam is provided by steam throttling (20%) and from the turbines exhaust (80%).

Pumps, on the other hand, enable the conversion of mechanical energy into the kinetic, potential, and internal energy of the ß uid. A submersible mixer transforms mechanical energy into ß uid energy to create water ß ow and achieve the mixing function.
