This example tests the configuration of two flow machines that are installed in series.
Both flow machines start with full speed.
At t=150 seconds, the speed of the flow machine on the left is reduced to zero.
As its speed is reduced, the mass flow rate is reduced. Note that even at zero input, the mass flow rate is non-zero,
but the pressure drop of the pump floMac1.dp is positive, which means that this pump has a flow resistance.
However, flowMac2.dp is always negative, as this pump has a constant control input of 1.
