1. A proposed four unit luxury apartment building includes the following in each unit: Kitchen sink Dishwasher Clothes washer Two bathtubs with shower Two lavatories Two water closets with flush tanks In addition, two hose bibbs are provided for the building. Each apartment is provided with individual water heating; a single water supply line provides all water required by each apartment (no separate hot and cold water line sizing). The service run to the most distant unit is 140' horizontal distance. The maximum height of connected items is 26' above the connection to the water main. a. Using the Water Supply Fixture Unit method, find the estimated maximum flow required for the building. (20 points) b. Based on a maximum velocity of 6 ft/sec for water flow, find the required diameter for water service to the building. (20 points) c. Based on water pressure at the main of 60 PSI and a double check-valve preventer with a 5 PSI pressure drop, find the required water meter size (the meter can be smaller than the building water service). (20 points) 1.
