Linear Resistance

Ideal linear pneumatic resistance

	Description
	The Linear Resistance component models the pressure differential proportional to the rate of fluid flow.

	Equations
	$p = p_{A} - p_{B}$ $mflow = B \cdot p$ $mflow = mflow__A = - {mflow}_{B}$ $hflow__x = inStream (portx \cdot hflow)$

Variables

Name	Units	Description	Modelica ID
$p$	$Pa$	Pressure difference across the component	p
$mflow$	$\frac{kg}{s}$	Mass flow rate through the component	mflow
${hflow}_{x}$	$\frac{J}{kg}$	Mass flow rate through the port $x, x \in \{A, B\}$	portx.hflow

Connections

Name	Description	Modelica ID
$portA$	Upstream Pneumatic port	portA
$portB$	Downstream Pneumatic port	portB

Parameters

Fluid Medium Parameters

The Gas parameters used in the equations, are properties defined in the Gas Model component used in the model.

Name	Default	Units	Description	Modelica ID
$Use default medium$	$true$		When true the default gas properties defined for Air will be used.	useDefaultMedium
$medium$	$-$		When Use default medium is false this option gets turned on. The user can specify the name of the Gas model dragged into the canvas.	medium

Conductance

Name	Default	Units	Description	Modelica ID
$B$	$1 \cdot 10^{- 10}$	$\frac{m^{3}}{s \cdot Pa}$	Pneumatic conductance (mflow/p)	B
