I was reading a paper and I saw a statement that says zero hydrostatic pressure. I was wondering what it means..
some people like to measure hydrostatic pressure by cutting off the atmospheric pressure part.they just assume atm. pressure zero.they measure it above or below atm pressure standard line ,also it depends on where you read it.
I have not said any word about gauge pressure.I was really mean that the constant of integration in simple pressure formula if put zero will give some absolute measurement of force and there will not be net force.if you have really gotten some conclusion out of my first post then it was not meant that way i.e. gauge pressure.however are you saying that the thickness of monomolecular level is zero so that it does not give rise to any hydrostatic pressure.A monomolecular layer of fluid will have zero hydrostatic pressure
Hydrostatic pressure is the pressure exerted by a fluid, such as water, at rest. It is caused by the weight of the fluid pushing down on an object or surface.
Hydrostatic pressure can be zero when the fluid is not in motion and there is no external force acting on it. This can occur in a container that is sealed and at rest.
The two main factors that can affect hydrostatic pressure are the density of the fluid and the depth of the fluid. The deeper the fluid, the greater the hydrostatic pressure due to the increased weight of the fluid above.
Yes, hydrostatic pressure can be negative. This usually occurs when the fluid is in a state of tension, such as when it is being pulled or stretched. In this case, the pressure is pulling inward instead of pushing outward.
Hydrostatic pressure is typically measured using a device called a manometer, which consists of a U-shaped tube filled with a fluid. The difference in height between the two arms of the tube indicates the hydrostatic pressure of the fluid being measured.
