Which formula represents the conversion of horsepower in wastewater treatment calculations?

The first choice accurately represents the conversion of horsepower in the context of wastewater treatment calculations by defining the relationship between power measured in horsepower and foot-pounds per minute. The formula states that power can be calculated by taking the product of the flow rate in minutes and horsepower, then dividing by 33,000.

This conversion factor of 33,000 foot-pounds per minute is significant because it is derived from the definition of horsepower: one horsepower is equivalent to 33,000 foot-pounds of work done in one minute. Therefore, if you have a certain horsepower value and you want to understand how much actual power that translates to in foot-pounds per minute, this formula allows you to do that by properly adjusting for the conversion factor.

Being aware of this foundational relationship is crucial when performing calculations related to energy and power in wastewater systems, as it helps ensure that the values used for flow rates and horsepower are accurately transformed into usable power metrics for the treatment processes.
