Pressure losses
Pressure loss in the high-pressure flushing hose (2)
As an example, the pressure loss (depending on the flow rate of the pump) is specified for different nominal sizes and materials of hoses in Figure 3 40. However, these data do not necessarily coincide with the actual pressure losses [FI-Hugo].
An additional increase of these pressure losses is to be expected, especially because, during use, one part of the hose is rolled onto the reel. In this case, the radius of the hose reel is decisive. The smaller the radius, the higher the pressure loss [Geib2002].
