The resistance coefficients (K-values) are calculated using the Hooper and Darby methods for the laminar and turbulent flow regimes. Friction factors are automatically calculated (using the Churchill equation) for all flow regimes. Changes in elevation from inlet to outlet are taken into account. The pressure drop for liquids is also expressed in terms of head of flowing fluid for pump sizing. The program includes data tables for pipe size and roughness. Units handling is unparalleled, allowing the units for any individual property to be set independently, or in predefined sets (US Customary, SI Units and Metric Units) and in user-defined sets of mixed units. Viscosities can be specified in dynamic or kinematic units.
