The end of the plunger has a tungsten wire extension that fits the entire length of the needle all the way to the tip, resulting in zero dead volume. If that does not work, a plunger puller could be used. If the object is reusable, place it in a secure, closed container after it has been used. If the plunger is inserted and the solvent is pushed through the needle, the solvent will be pushed through the needle. Perhaps someone more familiar with fluid dynamics can tell us what the real profile is, but I expect this will come close enough for the purpose of increases the energy requirement due to the spread of flow speeds. It makes me feel like Im not the only one. And you don't need to include the atmospheric pressure because that is going to cancel out. Most of us started at .25Which would be between the .2 and .3. What are the different parts of a barrel? Its all about pressure. Welcome on the site! The first is the size of the syringe.
