compensation tank

[Ing Italy]

Good evening,

I would have the following question about a water distribution network at constant flow with compensation tank.
the constant flow that comes to the compensation tank I would say that it is set me by the characteristic curve intersection of the pumping group with the resistant curve of the circuit that from the pump group comes to the reservoir...the variable flow out of the tank has as energy only static pressure of the fluid contained in the tank? .if I have a circuit out of the tank with high load losses, then with characteristic curve resistant dp-q close to the vertical and I have a level of liquid in the tank very low risk of not having sufficient pressure to get out the fluid? .
consider the case where there are no significant differences of share between the outlet of the tank and the final user, could I still have problems according to you? .

I thank you if you want to give me some imbeccable about it.

Okay.

in the spirit of the forum, it would be appreciated that you would also post as you solved, in the future could come useful to others. :finger:

Hi.

I would say that at the usual use formula of bernoulli to find me the minimum level of fluid in the compensation tank that guarantees me the sufficient overpressure for the outflow of the fluid and the achievement of the user thus compensating for any leaps of quota, any kinetic differences and load losses. ..so that for 1 bar of overpressure with water I need about a column of fluid of 10 meters it is evident that this solution can only use it when required low overpressions, hello!
