The dasked line is the relationship predicted for a small contribution of sodium ions to the membrane potential (Hodgkin and Horowicz, J Physiol (Lond) 145:405-432, 1959). Basically you can calculate the hydraulic pressure based on the elevation (don't forget to add what's in the tank), use that to determine your final velocity, and then use that to determine your flow rate based on your pipe size. The difference in potential between two points is related to the work done in moving a point charge from the first point to the second. Visualizing 'equipotential lines', one can see that streamlines (as long as we are considering 2D incompressible flow, we can talk about stream lines), will be perpendicular. Critical to Extreme fire weather conditions continue across parts of northern and southern California into Thursday. While some watersheds have flowing water throughout the year, it is often the responsibility of water managers to distribute the water between uses.
