1. COPPER PIPE SIZING PROGRAM ProVersion

2. PRO CALCULATOR WILL WORK ON PHONE OR PC (and offline) ENTER START PRESSURE say 40m=392.4 kPa ENTER NUMBER OF DWELLINGS LENGTH TO WORST CASE HEIGHT DIFFERENCE between start and end locations ANSWERS Keep clicking anywhere to proceed 392.4 30 12 15 3.0 10 40 m 15 Min residual head 10 32 1.937 0 1.94

3. CHECK WITH CODE ANSWERS 40 m 15 10 RESIDUAL HEAD IS 10m Pressure Drop = start – Ht. diff – residual = 40 – 15 – 10 = 15m Pressure Drop 15 m 392.4 30 12 15 3.0 10 32 1.937 0 1.94

4. 392.4 30 12 15 3.0 10 32 1.937 0 1.94 CHECK WITH CODEPressure Drop = 15m From Code table 3.2, flow from 12 dwellings = 1.94 L/s From table C1 the closest higher flow for length 30m is 2.02 L/s. This gives the required pipe size = 32mm

5. 392.4 30 12 15 3.0 10 32 1.937 0 1.94 A table is also produced showing the capacities of each pipe section

6. 392.4 30 12 15 3.0 10 32 1.937 0 1.94 A table is also produced showing the capacities of each pipe section From previous: Pressure Drop = 15m Size from previous = 32. Length = 30 Agrees with results Flow = 2.02 CODE

7. Ability to enter fixtures as well as dwellings 22 10 5 5 1.25 Flow is calculated Flow is transferred to main screen Flow is totalled Fixed Flows ie Hose Reels can be added

8. If the pressure is too low, pump duty is calculated Use this pressure as the start pressure to calculate pipe sizes when using the pump.

11. ADVANTAGES OVER THE CODE QUICKER AND EASIER THIS PROGRAM PRODUCES A TABLE FOR EVERY POSSIBLE PRESSURE DROP WITH NO UPPER LIMIT THE CODE PRESSURE DROP TABLES ARE IN INCREMENTS OF UP TO 5M, AND ONLY GO UP TO 35M THE INDEX LENGTH IS ALSO INCREMENTED BY 5M THIS PROGRAM PRODUCES A TABLE FOR EVERY POSSIBLE INDEX LENGTH THE ADVANTAGE OF THIS IS THAT THERE IS NO NEED TO INTERPOLATE BETWEEN THE FIGURES IN THE TABLES, OR ACCEPT A POSSIBLY LARGER SIZE THAN REQUIRED.
