Pressure Loss

Pressure Loss

The pressure loss in corrugated hoses is 100% higher than in new welded steelpipes, because the bore of a corrugated hose is not smooth. This means that inthe case of corrugated hoses an increase in diameter of 15% is required to reducethe pressure loss to the value of the pressure loss in steel pipes.

The chart shows the approximate pressure drop for each size of corrugated hoserelated to a flow rate where water is the fluid. To utilize the chart, read off onthe base line the flow rate required. Where vertical line from the selected pointon the base line intersects the nominal bore line, the pressure drop is shown onthe vertical axis, corresponding to the point inter section.
