    The Pressure loss in corrugated hose is 100% higher than in new welded steel pipes. This means that in the case of corrugated hose an increase in diameter of approximately 15% is required to reduce the pressure loss to the value of pressure loss in steel pipes.

    To utilise the chart…

    1. Identify the flow rate required on the base line (Horizontal Axis).
    2. Where the vertical line, that references to the nominal bore of the hose, intersects a horizontal line - Establish the pressure drop on the Vertical Axis.
