PerteDP — Thermal-hydraulic pipe
Description
A PertDP block represents a hydraulic pipe with linear resistance losses. This component represents a hydraulic resistance and pressure loss is directly proportional to the flow rate. Conventionally, the flow direction is the positive when fluid flows from the black port to the white port. The pressure loss is obtained
with
. The key parameters of this block are the pipes' length, the pipe's diameter, inlet and outlet altitudes, and some other thermal-hydraulic coefficients.
