Question 1
Q1A municipal water treatment plant manager is analyzing the flow rates of two main water pumps, Pump A and Pump B, over a 24-hour period to identify potential inefficiencies. The operational specifications require that neither pump should operate below 85% of its maximum capacity for more than 4 consecutive hours. Analyze the provided performance chart.
Based on the chart and the operational specifications, what is the primary operational issue that requires immediate attention?
Show answer & explanation
Correct answer: C
The correct answer is that Pump A has violated the operational specification. The specification states that pumps should not operate below 85% capacity for more than 4 consecutive hours. The Gantt chart clearly shows that Pump A was in the 'Below 85% Capacity' state for a duration of 5 hours (from 02:00 for 5h). This exceeds the 4-hour limit, indicating a compliance violation that needs attention. Pump B's period of low capacity was only 3 hours, which is within the acceptable limit.
