Which calculation would give the height of a vent needed for proper drainage?

X=1/(.0408x.5625)
X=1/.02295
X=43.57'
None of the above

The correct answer is: X=43.57'

The height of a vent needed for proper drainage is calculated based on the specific requirements and codes for plumbing systems, which dictate the minimum height for vents above the fixture they serve. In this instance, the result of 43.57 feet represents the required height for a vent to ensure that the drainage system operates effectively. Such calculations typically take into account factors such as the fixture's height, the type of drainage system, and local building codes. When the formulas provided in the other choices are evaluated in the context of vent height calculations, they either do not align with common plumbing practices or fail to yield a realistic vent height according to plumbing code requirements. Therefore, the conclusion is that 43.57 feet is correct because it meets the necessary height guideline to facilitate proper drainage and venting, ensuring the system maintains an adequate airflow and prevents negative pressure, which could lead to drainage issues.
