Counter flow parallel flow

WebFlow configuration (or arrangement) refers to the geometric relationship between the fluid streams, relating to the fluid flow paths. In parallel-flow (Fig. 1(A)) the two streams enter the HEX on the same side, flow parallel to each other, and leave on the other side of the HEX, while in counter-flow (Fig. 1(B)) the fluids flow in opposite directions. http://ww2.che.ufl.edu/ren/unit-ops-lab/ech4224L/HE/HE-theory.pdf
