What is the maximum positive differential pressure allowed?

The maximum positive differential pressure allowed is determined by safety standards and operational limits to ensure that systems can function without risking failure or hazardous conditions. In this context, a differential pressure of 8.7 psi is significant because it represents a threshold that systems can safely handle without compromising their integrity.

Differential pressure refers to the difference in pressure between two points in a system, and maintaining it within safe limits is crucial for preventing issues such as equipment failure, leaks, or other safety hazards. The specified value of 8.7 psi is based on extensive testing and theoretical calculations which provide a balance between optimal performance and safety.

Other values provided may exceed recommended limits for certain applications, risking possible operational failure or unsafe conditions. This makes the 8.7 psi designation a vital point of reference in practical applications.
