Atmospheric Pressure

Atmospheric pressure of a Pneumatic network

	Description
	The Atmospheric Pressure component provides a connection to atmospheric pressure in a Pneumatic circuit. Every Pneumatics network should contain a connection to this component.

	Equations
	$p = p_{A} = P$ $mflow = {mflow}_{A}$ $hflow = Function (p__atm, T__env, c__p)$

Variables

Name	Units	Description	Modelica ID
$p$	$Pa$	Pressure at component	p
$mflow$	$\frac{kg}{s}$	Mass flow rate into component	mflow
${hflow}_{X}$	$\frac{J}{kg}$	Specific Enthalpy into port X	hflowX

Connections

Name	Description	Modelica ID
$portA$	Pneumatic port	portA

Parameters

Name	Default	Units	Description	Modelica ID
$P$	$101325$	$Pa$	Atmospheric pressure	P

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
$Use default medium$	$true$		When true the default gas properties defined for Air will be used.
$medium$	$-$		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.
