The TDH in your example should be = Static head - friction head

Can you please recommend some technical sources for the calculations that would be useful in making these determinations? i.e. like you have described above. Simple would be better, just to highlight the concepts and theory that one would employ in sizing a residential water booster pump. It doesn't have to be overly complex or detailed for my application. Thanks.

Very informative video. Do you have time to answer a question for me? I have a cylinder filled with water, There's a small hole in the top that I can open and close. There's a hole in the bottom that I can open and close, just to control whether or not water is released. If both holes are closed, obviously no water is released. If the cylinder is filled to the top and I open the bottom hole, no water is released until I open the hole at the top. If I open the top hole very briefly, some water is released but stops very quickly after I close the hole at the top. If the cylinder is only two-thirds full, the flow continues for a longer amount of time after I close the top hole. If it's one-third full, it takes an even longer time to stop flowing. Can you tell me why it works this way? I'd be most appreciative if you can answer this question. Thanks very much!

The behavior of the water in your cylinder can be explained by the principles of fluid dynamics and air pressure. 1. Both Holes Closed: When both the top and bottom holes are closed, no water is released because there is no way for air to enter the cylinder to replace the water that would flow out. This creates a vacuum effect that prevents water from leaving the cylinder. 2. Opening Bottom Hole with Cylinder Full and Top Hole Closed: When the cylinder is full and you open the bottom hole while keeping the top hole closed, no water flows out because the air pressure inside and outside the cylinder is balanced, and there's no air entering the cylinder to displace the water. 3. Opening Top Hole Briefly: When you briefly open the top hole, air enters and allows some water to flow out from the bottom. However, as soon as you close the top hole, the air flow stops, quickly creating a vacuum again and stopping the water flow. 4. Varying Water Levels and Flow Duration: The differing durations of flow when the cylinder is two-thirds or one-third full can be attributed to the amount of water and air inside the cylinder. When the cylinder is less full, there is more air space above the water. Opening the top hole allows more air to enter before a vacuum is re-established when the hole is closed. The larger volume of air takes longer to be expelled by the escaping water, hence the flow continues for a longer time. This phenomenon illustrates how both air pressure and the presence of air in a container can influence the movement of a liquid in a system. It's a practical demonstration of basic principles in physics related to fluid dynamics and pressure equilibrium.
