Reference: Calpeda pressure tank volume calculaton

Vt= (Qm/4xZ)x1/1-((P2-2)/P1)

Vt: Total volume of air cushion vessel in m3

Qm: Average pump flow in m3 Qm= (Qmin + Qmax)/2

Qmin: Minimum pump flow in m3

Qmax: Maximum pump flow in m3

P1: Maximum set pressure of pressure switch

P2: Minimum set pressure of pressure switch

Z: Mazimum nuber of starts/hours allowed by the motor

Qmin: m3/h Recommendation

Qmax: m3/h Recommendation

Qm: 11 m3/h

P1: 45 m

P2: 20 m

Z: 21 time Recommendation

Vt= 0.218254

Thus, Pressure tank capacity: 219 Liters

If, Pump is inverter, so, safety factor 25 % Recommendation

Thus, Pressure tank capacity: 55 Liters
