head and pressure on junction are over than reservoir's head

[Pandi Hardiansyah Sitorus]

please help me

My reservoirs total head it's only 30 m

but head in every junction is more than 69 m

and the pressure more than 45 m

what shoul i do to make head in reservoirs suit with every junction ?

fyi. elevation on reservoirs and every junction almost same

[Mark Scott]

You have a pump directly after the reservoir at a generated head of 30m, thus the suction pressure is 30m (head of reservoir) plus pumping head is 30m which gives a total discharge pressure of 60m.

 

Pressure = Head (HGL) – Elevation.

You have a pump downstream of the reservoir that is adding approximately 40 feet of head/pressure to the system.

the total head at the reservoir is kept at low water elevation may be 20m and demand multiplier (may be 6)  has to suitably applied.

what purpose your adopting this network and whether for model paper work to learn epanet2 or real field problem.

if it is real field network, tell me about the about per-capita demand and newly planning & new design, what is the purpose of your network

and what are the target results actual you required.

Later on we can solve your problems.
