Difficulty: HardQuantitative Detail Extraction

During routine inspection of the auxiliary hydraulic assembly, technicians must first depressurize the secondary reserve tank to 15 psi before disconnecting the main feedline. The primary operating pressure runs at 3,200 psi under standard load, but during high-velocity maneuvers, internal pressure spikes up to 4,500 psi. If the thermal relief valve detects a baseline pressure exceeding 180 psi while the system is idling, maintenance protocols require an immediate emergency purge. System calibration must be verified every 48 operating hours.

According to the passage, at what threshold pressure during system idling does the thermal relief valve mandate an emergency purge?

  1. A
    15 psi
  2. 180 psiAnswer
  3. C
    3,200 psi
  4. D
    4,500 psi

Answer

180 psi
The passage explicitly indicates that maintenance protocols mandate an emergency purge when the thermal relief valve detects baseline pressure exceeding 180 psi while the system is idling.

Step-by-Step Solution

1
Identify the key conditions specified in the prompt
Identified condition: 'thermal relief valve', 'system idling', and 'emergency purge'.
The question asks for a specific numerical threshold associated with a unique operational state.
2
Scan the passage for the matching clause and operational context
Located sentence: 'If the thermal relief valve detects a baseline pressure exceeding 180 psi while the system is idling, maintenance protocols require an immediate emergency purge.'
Direct textual retrieval connects the specified mechanism and condition to its exact quantitative measurement.
3
Extract the corresponding quantity and eliminate competing data points
The numerical value linked to the idling purge mandate is 180 psi.
Other numerical figures in the text correspond to reserve depressurization (15 psi), standard load pressure (3,200 psi), peak maneuver pressure (4,500 psi), and calibration intervals (48 hours).
