Figuring head pressure in piping

WebThe pressure loss per length of pipe is 331 Pascals per meter. Darcy-Weisbach Equivalent Length. When the pressure vs. flow characteristics of valves and fittings are expressed as an equivalent length of pipe, the Darcy-Weisbach equation can be used to determine the minor pressure or head loss through those components by substituting the valve or … WebAug 21, 2024 · the static head, or height difference, between the liquid level in Tank A and the liquid level in Tank B; the friction head, or the pressure losses caused by the flow of liquid through the pipe and fittings, between Tank A and Tank B. In the example, the velocity head will balance out to zero, as centrifugal pumps provide pulsation-free flow.
