PRESSURE DROPS
The water flow rate is calculated with the following formula:
Q = Pc x 860 / ΔT.
Q Water flow rate (l/h)
Pc Cooling capacity (kW)
ΔT Water heat drop (°C)
Pressure drops are calculated with the following formula:
Δp = K x (Q)2
Δp Pressure drops (kPa)
Coefficient for the various sizes and versions
