The baffle supports must be designed to handle the torque input
by the mixer.  Mixer torque should be calculated using the motor
power and dividing by pi times the mixer shaft speed, with the
proper conversion factor for units.  The torque formula for
power in horsepower, shaft speed in revolutions per minute, and
torque in inch-pounds is torque [in-lbs] = 63025 * motor
horsepower [hp] / output shaft speed [rpm].  Note that the
correct speed to use is the mixer shaft speed, not the motor
speed.  A speed reducer is a constant power device and a torque
increaser.  A variety of methods can be used to get from the
input torque to the baffle loads.  The simplest method is to
simply distribute the torque input to a force load on each
baffle, dividing by the number of baffles and the distance from
the tank center to the tips of the baffles.  Then the baffle
thickness, supports shape, number of supports, etc. must be
designed with adequate strength.   Using maximum design limits
