If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.

What is high static pressure?
The static head the distance to the point of application or the height the pump has to overcome for liquids. For air likewise is almost the same except that it is ducted, refer to Moody chart.The pressure exerted by a still liquid or gas, especially water or air.
Why is the earth's inner core solid even though its temperature is hotter than that which would melt iron?
Mantle? the iron remains solid because the pressure exerted by the rest of the planet due to gravity contains the iron element and prevents its liquification.
An empty office chair is at rest on the floor Consider the following forces Gravity Upward force exerted by the floor A net downward force exerted by air What forces are acting on the office chair?
All three of the forces are acting on the office chair.
Does decreasing pipe diameter increase water pressure?
No. Pascal's Principle states that a pressure applied to a fluid system at rest is felt throughout the entire system. This means that, regardless of pipe diameter, city pressure is felt everywhere. Decreasing pipe diameter will only reduce the flow rate of the water, due to more head loss when the water moves.
What happen when a magnetic needle is freely suspended?
it will rest in the north - south direction
What is the difference between static pressure and dynamic pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
What is the Difference between Dynamic pressure and static pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
What is stagnation pressure?
Static pressure is the pressure exerted by fluid in all directions, when it is in rest. Stagnation pressure is the sum of static and dynamic pressure of fluid in motion. Dynamic head is given by (velocity)^2/2*g.
What is high static pressure?
The static head the distance to the point of application or the height the pump has to overcome for liquids. For air likewise is almost the same except that it is ducted, refer to Moody chart.The pressure exerted by a still liquid or gas, especially water or air.
What is hydrostatic pressure used for drilling oil wells?
In Drilling terminology, hydrostatic pressure is "The pressure exerted on a column of fluid at rest". This said, an oil well is just a column of fluid. Hydrostatic pressure is used to control the formation pressure in a well in order to prevent a "kick" (an influx of fluid into the well bore) or a blow-out (an uncontrolled influx of fluid into the well bore). Hydrostatic Pressure is calculated by a simple calculation = depth in meters x weight of drilling fluid in kg/m3 x gravity constant of 0.00981. IE. drilling at a depth of 3459m with drilling fluid that weighs 1120 kg/m3 would give you a Hydrostatic pressure of 38005 kpa. This is the amount of pressure that is being exerted on the formation at 3459m
Explain hydrostatic pressure?
Hydrostatic pressure is the pressure exerted by a liquid when it is at rest. It is directly proportional to the height of a liquid column of uniform density.
What is An action exerted on a body in order to change the body's state of rest or motion force has magnitude and direction?
a force lil' G !!
What is static load on machine tools?
The static load of a machine tool is the pressure exerted by the base of the machine (at rest and without a workpiece or tooling loaded).
Which direction does a buoyant force act in?
A buoyant force is produced when an object is completely or partially submerged in a fluid at rest .
Define systolic and diastolic blood pressure?
Blood Pressure: The force at which blood flows through the arteries in the body. Systolic: Refers to the pressure on the arteries as the heart contracts (squeezes). Diastolic: Refers to the pressure on the vessels as the heart relaxes.
What type of blood pressure is produced when the heart is in a relaxed state?
The measurement of blood pressure results in two numbers: the systolic blood pressure and diastolic blood pressure. This is expressed as a fraction: systolic over diastolic. The diastolic blood pressure is produced when the heart is in a relaxed state. It is the measure of the pressure exerted on the arteries during diastole, or relaxation.
What is dynamic pressure?
1: the pressure on a surface at which a flowing fluid is brought to rest in excess of the pressure on it when the fluid is not flowing2: the quantity of air measured by most airspeed instruments and equal to the product 1⁄2 ρV2 where ρ is the density of the air and V is the relative speed of the air
