RESIDUAL HEAD IS 10mPressure Drop = start – Ht. diff – residual
= 40 – 15 – 10 = 15m

CHECK WITH CODE Pressure 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

Flow is calculated
Flow is transferred to main screen
Flow is totalledFixed Flows ie Hose Reels can be added
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.

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.
