    Downwards

    Hence pressure is always directed to the downwards direction. However the pressure direction may also be other direction, if the object is moved with an acceleration in any direction. However the most common force on a liquid is the gravitational force, and so the pressure is downward.

    Which direction does the liquid pressure act?
    The liquid pressure acts in all directions. The diagrams show, to the same scale, the vertical sections of a set of circular vessels. Each vessel contains the same depth of water.

    What is the direction of pressure in a static fluid?
    Pressure at a point in a static fluid is independent of direction. The force exerted by the walls on the liquid will be pointing inwards. Imagine if there is a hole in the container and water is liquid out, it is easy to see that you have to apply a force inwards in order to prevent the liquid from leaking.

    Why is the pressure in a liquid different at different depths?
    The pressure in a liquid is different at different depths. Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom ...

    What is the pressure at the surface of a liquid?
    For example, atmospheric pressure at sea level is about 100,000 Pa, but it is only about 21,000 Pa at the cruising height of an airliner. Just like the atmosphere, liquids exert pressure on objects. The pressure in liquids changes with depth. The deeper you go: Liquid pressure is exerted on the surface of an object in a liquid.

    May 03, 2021 · Pressure is inversely proportional to velocity, so we have lower pressure at the exit of the nozzle. But as per definition of pressure, P=F/A, i.e., pressure is inversely proportional to the area which contradicts the above explanation on basis of continuity and Bernoulli equation.

    May 06, 2017 · The pressure of a liquid can be made negative and liquids can exert significant amount of tension. But since the liquid has no shear strength, the tension/negative pressure would be isotropic. Since ggases and supercritical fluids have no surface tension, they cannot be put under negative pressure, unlike liquids.

    Pressure is a scalar and does not have a direction. This is discussed in some detail in the answers to Define Pressure at A point. Why is it a Scalar?, though this might be a bit technical. When you measure a pressure you are actually measuring the force applied to a surface.

    Nov 18, 2019 · In downward direction the liquid pressure always directed. Option: (b) Explanation: Pressure can be defined as the force exerted per unit of volume. Now the force is due to the weight of the liquid. Now the weight is always directed downwards due to the gravitational pull of the earth. Hence pressure is always directed to the downwards direction.
