Final answer:
The differential pressure required to trip a Pressure Relief Valve is specific to the valve's design and should be provided by the manufacturer or found in the system design documentation. The reference information does not adequately answer the question as it doesn't specify the PRP valve in question.
Step-by-step explanation:
The question pertains to the operation of a Pressure Relief Valve (PRV) or Pressure Release Diaphragm and the differential pressure required to actuate it. This is a concept in the field of engineering, specifically within the domain of mechanical engineering and fluid dynamics.
Typically, the exact trip pressure for a PRV is determined by the design and specifications of the valve. In general, the pressure difference (the differential pressure) necessary to trip a PRV is a design parameter that should be obtained from the manufacturer's data or the design documentation of the system in question.
The provided reference information does not directly address the value of the differential pressure required to trip a PRP (Pressure Release Valve); however, it covers various aspects of gauge pressure and how different pressures interact in a fluid dynamics context.
As such, it is not possible to give a definitive answer without the correct specifications or context. For accurate and precise operation, consulting the valve's documentation or reaching out to the engineering team responsible for the system setup would be required.
