Detailed Description

CurveFunctionalPressureDrop is a Curve that wraps the OpenStudio IDD object 'OS:Curve:Functional:PressureDrop'.

The functional form is

$$\displaystyle \begin{array}{lll} \Delta P = \left(K + f \cdot \frac{L}{D} \right) \cdot \frac{\rho V^2}{2}\\\\ \text{Where:}\\\\ K & = & \text{minorLossCoefficient}\\ f & = & \text{calculated from roughness and Moody-chart, or set by fixed friction factor}\\ L & = & \text{length}\\ D & = & \text{diameter}\\ \rho & = & V\ \text{from plant simulation}\\ \end{array}$$
