Course Competencies (Course Outcomes)
  1. Determine building demand
    Assessment Strategies
    by determining the building demand on a written exam
    using tables 82.40-1 and -2 and -3 in the code
    Criteria
    you have a complete fixture list
    you have identified public and non-public fixtures
    you have identified bathroom groups
    you have identified continuous flow devices
    you have determined whether the system is predominately flushometer or predominately flushtank based upon GPM
    you interpolate between values given on table 3

  2. Calculate uniform pressure loss
    Assessment Strategies
    by determining the pressure available for uniform loss on a written exam
    given the water calculation sheet
