BOLD NUMBERS INDICATE EXTRA HEAD CREATED BY PIPE RESISTANCE IN METRES PER 100m RUN
PIPE RESISTANCE CHART EXAMPLES:
300m of 1 /2” pipe with 70 l/m flow ..... i.e.: at 70 l/m 11/2” pipe requires 3m extra head for each 100m.
Therefore 3 x 3m = 9m extra static head.
500m of 2” pipe with 200l/m ..... i.e.: @ 200 l/m 2” pipe = 7m head.
Therefore 7 x 5 = 35m extra static head.
