Dynamic head calculation for pump
Did you know?
In fluid dynamics, total dynamic head (TDH) is the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe. TDH = Static Height + Static Lift + Friction Loss + Velocity Head where: Static height is the maximum height reached by the pipe after the pump (also known as the disc… WebThe performance of the pump at a certain speed (RPM) can be found in the manufacturer’s datasheet displayed as the flow rate (Q) versus head curve (figure 2). At the maximum head (circled in red), the pump has zero flow or little. This is often referred to as the shut-off head. When looking for a pump, ensure that the head provides a ...
