Sizing Plumbing Water System

Plumbing water distribution systems are designed on the idea of the most probable peak demand loading, which reflects the worst-case scenario for a system. These types of systems require different considerations than large-scale water distribution networks. The difference is primarily attributed to uncertainty regarding the use of plumbing fixtures, hence uncertainty in demand loadings. This 3-hour course provides comprehensive design methodology and underlying principles of plumbing water...
