PRESSURE LOSS OF THE HEAT EXCHANGERS
The following diagram shows the hydraulic pressure
losses of the various heat exchangers. The data was de-
termined at an average water temperature of 10 °C. To
determine the pressure losses depending on the wa-
ter temperatures, the determined pressure loss can be
multiplied by the corresponding correction coefficients
from the following table:
