WATER PRESSURE DROP
Desuperheaters
The graph below illustrates the water pressure drop values in kPa depending on the flow rate in liters/second. The operating range is delimited by the
minimum and maximum values given in the next table.
The graphs are referred to units operating with water at the temperature of 10°C (density 1000 kg/m
3
).
