Final answer:
The 'sensitive Leak Test' method mentioned in the question refers to an engineering practice of applying test pressure to a component. The test pressure applied is the lesser of two values: a specific psi or a percentage of the design pressure. The example provided also requires statistical analysis to determine pressure tolerances of different valves.
Step-by-step explanation:
The phrase "sensitive Leak Test" method is related to an engineering procedure where a component, such as a valve or pressure vessel, is tested for leaks by applying pressure. This procedure is critical in industries where pressure integrity of components is essential.
The typical protocol states that the test pressure should be the lesser of a certain value in psi (pounds per square inch) or a specified percentage of the design pressure of the component being tested.
As for the example, comparing two valves for their pressure tolerances, a statistical approach is used. A sample of 100 of each valve type is tested and the number of valves that cracked (failed) under a pressure of 4,500 psi is noted. Statistical analysis at a 5 percent level of significance is employed to determine if a significant difference exists between the pressure tolerances of the two valves.
On the other hand, when referring to Boyle's law or examples of pressure measurements in different units, these are related to the principles of gas laws in physics and chemistry, where pressure, volume, and temperature relationships of a gas are analyzed.
