The white-shaded cells accept input from the designer. For instance, fixture counts from the given information arc entered in Column |_BJ; the corresponding recommended fixture flow rates arc already provided in Column |_DJ. The flow rates in Column [D] may be reduced only if the manufacturer specifics a lower flow rate for the fixture.Column [E] establishes the upper limits for the flow rates entered into Column [DJ.

Solution: Step 2 of 2 Building Supply. Chart A 105.1(1) for copper piping systems (from Appendix A of the UPC, shown in Figure 3) is used to determine the pipe size, based on given friction loss* given maximum allowable pipe velocity, given pipe material and the demand load computed in Step 1 . In Figure 3, the intersection of the given friction loss (15 psi) ( 103 kPa) and the maximum allowable pipe velocity (10 ft/s) (3.05 m/s) is labeled point A. The vertical line that descends from point A to the base of the chart Determine the Pipe Size of the intersects four nominal sizes for L-coppcr pipe. These intersection points arc labeled B, C, D, E and correspond to pipe sizes of 1 inch ( 25 mm). inch (20 mm), Vi inch (15 mm) and Vs inch (10 mm), respectively. A horizontal line from points LL C. D, L to the right-hand sideof the chart gives maximum flow rates of 24 gpm ( L5 L/s)* 12 gpm (0.757 L/s), 4.5 gpm (0.28 L/s), and 2.3 gpm (0.145 L/s). respectively. These results arc summarized in Table 1 which shows that a 3A inch (20 mm) type L copper line is the minimum size that can convey the peak water demand of 8.5 gpm (0.54 L/s).

APPENDIX M tion process. Because fixturesfor outdoor water use may operate continuously for very long periods, they arc not included in the WDC To account for water use from one or more outdoor fixtures, add the demand of the single outdoor fixture with the highest flowrate to the calculated demand for indoor water use. With two hose bibbs, the demand of only one hose bibb is included. Hence, in this example, the total demand forthe whole house is 8.5 gpm (0.54 L/s) + 2.0 gpm (0.13 L/s) = 10.5 gpm 0.662 L/s). Solution: Step 2 of 2 — Determine the Pipe Size of the Building Supply. Table 1 shows that at 10.5 gpm (0.662 L/s) the building supply shall be 3A inch (20 mm) in diameter. As illustrated in Example 2, the hose bibb will increase the total demand for the w hole house to 13 gpm (0.820 L/s). Note that a reset button is provided to clear any numbers in Column [BJ from a previous calculation. Solution: Step 2 of 2 — Determine the Pipe Size of the Building Supply. Table 1 shows that at 13 gpm (0.820 L/s) the building supply shall be 1 inch (25 mm) in diameter Example 4: Sizing Branches and Risers-For individual hot and cold branches, repeat Steps 1 and 2. For example, for the hot water branch at the water heater [Figure 1, Pipe Section 3], enter all the fixtures and appliances that use hot water into the Water Demand Calculator (toilets will be excluded ) as seen in Figure 5. Use the calculated demand load to find the pipe size in Step 2. Table 1 show s that at 7.7 (0.49 L/s) gpm, the hot water branch shall be 3A inch (20 mm) in diameter. For each additional hot and cold branch [Figure 1, Pipe Sections 1 and 2], enter the number of fixtures and appliances served by that branch into the WDC and use that demand in Step 2 to determine the branch size. If the branch serves a hose bibb, add the demand of the hose bibb to the calculated demand flow for the branch. As discussed in Example 2, the hose bibb is not to be entered into WDC, since the Calculator is for indoor uses only. When there is only one fixture or appliance served by a fixture branch, the demand flow shall not exceed the fixture flow' rate in Column [E] of the Water Demand Calculator. The fixture flow rate would be used in Step 2 to determine the size of the fixture branch and supply. Example 3: Indoor, Outdoor and Other Fixture Water Use -Find the pipe size for the watersupply [Figure 1 , Pipe Section 4J| if the building in Example 2 adds a kitchen pot filler and a dog bath each writh a faucet flow rate of 5.5 gpm (0.35 L/s). Solution: Step 1 of 2 — Find Demand Load for the Buildiug Supply. The kitchen pot filler and dog bath are not listed in Column [A] of the WDC. To accommodate cases such as this, the WDC provides up to three additional rows for L4Other Fixtures". Enter the kitchen pot filler and dog bath in Column [A] of the WDC and erne: :hc fixture count for each in Column [B]. Find an indoor fixture that has a similar probability of use in Column [CJ and add that to the column. Finally, enter the flowr rate of the kitchen pot filler and dog bath in Column [D].
