For a constant horsepower/variable torque (CH/VT) load, an increase in operating speed requires a(n) ___ in torque.

For a constant horsepower/variable torque (CH/VT) load, the relationship between horsepower, torque, and speed is governed by the formula:

[ \text{Horsepower} = \frac{\text{Torque} \times \text{Speed}}{5252} ]

In this equation, horsepower remains constant while speed increases, which implicates a corresponding adjustment in torque. As the speed increases, to maintain constant horsepower, the torque must decrease. This is because horsepower is a product of both torque and speed; thus, if one variable increases, the other must decrease to keep the product constant.

In a CH/VT application, this relationship is vital for understanding how machinery operates under various conditions, particularly when speed settings change during operation. Recognizing that a higher speed necessitates lower torque allows for appropriate adjustments in design and operation to ensure efficiency and prevent mechanical failures.
