What is the BHP for the pump curve mentioned in the text?

The brake horsepower (BHP) for a pump is a measure of the power required to drive the pump when it is transmitting a certain flow against a specific head. To determine the BHP from a pump curve, one typically considers factors such as the flow rate, the total dynamic head, and the efficiency of the pump.

In this case, if the correct answer is identified as 130, it indicates that the pump's specifications, including its performance characteristics under ideal operating conditions, lead to a calculated horsepower requirement of 130. This figure may come from a comprehensive understanding of how the pump performs at specific flow rates and heads, as provided in the pump curve data.

Understanding the context of why 130 is the BHP would usually involve analyzing the performance and efficiency curves provided, making it clear that this power requirement is essential to ensure that the pump can operate effectively without risking damage or inefficiencies during operation. Thus, confirming the importance of both the correct flow rate and head pressures discussed in the pump curve analysis.
