WebA segment, called the baffle cut, is cut away to permit the fluid to flow parallel to the tube axis as it flows from one baffle space to another. The spacing between baffles is called the baffle pitch. The baffle pitch and the baffle cut determine the cross-flow velocity, and so the rate of heat transfer and the pressure drop.

Webthe baffle openings (known as baffle cut) and baffle spacing, it is possible to vary the heat transfer rates. By using the proper baffles, the flow dead points in the shell can also be removed.
