ABSTRACT
In this section a brief summary of the most general form of Bernoulli’s equation for steady incompressible “ows is introduced. Bernoulli’s equation is composed of kinetic energy, potential energy, and internal energy. The energy equation is written between the inlet at point 1 and the exit of the pipeline at point 2 (Figure 2.1). The process “ow diagram (PFD) represents sudden contraction (the exit of the ”rst tank to the inlet of pipe 1), two 90° elbows, and sudden expansion (the exit of pipe 4 and the inlet of the second tank).
