Fluid viscosity, inlet and outlet temperatures, tube side: number of tube sides, tube diameter, total number of tubes, turbulence generator type or tube cross-section type for non-straight (circular) tubes； Shell side: number of shell sides, tube type, tube sheet arrangement, baffle spacing. Tubes, shell side, etc.

The shell-side pressure drop is smallest for baffles of the same diameter. There is also the relative flow velocity of the media inside and outside the pipe.

The baffle rod is suitable for top condensation.
