• The pump is to be connected to a rising main which
has a diameter (D) of 400 mm and a length of 137
m.The entry exit and minor head losses in the
pipeline can be taken as 80D in this particular
situation. The friction loss can be approximated
by h; = ALQ² / 1 2D5 with A=0.04. The static lift is
10 m. By considering a single pump (P). And two
of the pumps in series (P+P) and parallel (P//P)
determine:
> the H-Q curve of the two pump combinations
» Which combination will be capable of discharging
at least 0.3 m³/s, with the ability to pump up to
0.35 m³/s if the need arises.
