Hello, please see attached text below - this concerns ''rigid column theory''. When a valve is closed, the pressure rises at the valve; the pressure rises above the reservoir pressure by ΔP with a height increase ΔH above H. When the valve is opened, this right hand pressure will disappear and the fluid will start to flow through the open valve.
Why is ΔH = H - Hf?
Why is ΔH = H - Hf?
