Water hammer pressure variation
Thread Content
In chemical production, water hammer often occurs, causing significant vibrations. I’m a bit confused as to why it generates such high pressure
If you don’t understand, that’s just right. . . . . . . . . . . . . . Bro, I don’t get it,,, Bro, I’m going to have a glass of water to calm down. .
Just treat it as a hammer; how much force do you exert when you swing a hammer to hit something
The volume of water vapor is 1,600 times that of the liquid. When it cools down and turns into a liquid, negative pressure is created, and the surrounding fluid rushes in rapidly, generating sound and vibration!
What the original poster is asking about is the cause of water hammer; what you mentioned, air impact, is not the same thing
It can be understood in this way: the propagation of water waves is accompanied by the transfer of energy. When the pump stops suddenly or a valve is closed, the energy of the water waves cannot be dissipated within a short period of time, which results in a shock force. This is similar to Newton’s law of momentum in high school physics, MV=FT – when the mass and velocity of the fluid remain constant, the shorter the time over which the force acts, the greater the shock force.
Water is formed due to pressure differences! It can appear in steam pipelines as well as in the outlet pipelines of pumps, especially at the outlets of large pumps!
