Diagrams
Picture 1 Pressure loss vs coolant flow
A line graph showing the relationship between pressure loss (in bar) on the y-axis and volume flow (in l/min) on the x-axis. The line starts at (0,0) and increases steadily, reaching approximately 0.8 bar at 35 l/min.
Picture 2 Allowed altitudes vs phase cable length
A line graph showing the relationship between altitude (in m) on the y-axis and phase cable length (in m) on the x-axis. The line starts at approximately 4500m at 0m cable length and decreases as cable length increases, reaching approximately 1000m at 17m cable length.
