Line chart showing flow rate in microliters per minute over time in seconds when opening the MV-1. A teal line shows the data for 2000 millibar fluid pressure, showing the flow rate peaking to above 2000 microliters per minute when the valve is opened and quickly settling to a steady 730 microliters per minute. A blue line shows the data for 700 millibar fluid pressure, showing the flow rate peaking to above 600 microliters per minute when the valve is opened and quickly settling to a steady 380 microliters per minute.
