What are dynamics for sudden water flow stoppage?
What are dynamics for sudden water flow stoppage?
(OP)
I test swimming pool drains-- sort of. I block the drain with a foam pad after establishing constant flow gpm. I take data and the pressure/time trace shows an initial sharp drop and then an oscillatory form on top of a decay back towards the pressure of the water head of the tank. Longer suction pipe lengths have longer periods.
Does anyone know if this can be modelled as a mass-spring damper system where the mass is the incompressible flow and the spring and damper properties are mainly in the foam? Would you know a good source of instruction/information?
