#include <flowControllers.h>
Supply a mass flow rate that is a function of the pressure drop across the valve.
The default behavior is a linearly proportional to the pressure difference. Note that real valves do not have this behavior, so this class does not model real, physical valves.

Set the proportionality constant between pressure drop and mass flow rate.
c has units of kg/s/Pa. The mass flow rate is computed as:
\[\dot{m} = c g(t) f(\Delta P) \]
where g and f are functions of time and pressure drop that are set by setTimeFunction
and setPressureFunction
, respectively. If no functions are specified, the mass flow rate defaults to:
\[\dot{m} = c \Delta P \]
