Pressure is scalar but force is a vector.

Pressure is defined as the force per unit area.

As we multiply area vector by the pressure which is scalar, we get the force vector. This is similar to get momentum vector by multiplying velocity vector by the mass which is scalar.

Unit of force is newton but unit for pressure is N m-2

Force produced by a pressure difference?

The force produced by a pressure difference can be calculated using the formula F = A * P, where F is the force, A is the area over which the pressure is acting, and P is the pressure difference. The SI unit for pressure is Pascal (Pa) and the unit for force is Newton (N).


How does air pressure affect lift on a kite?

Air pressure affects lift on a kite by creating a pressure difference between the top and bottom surfaces of the kite. This pressure difference results in a force called lift that allows the kite to rise and stay airborne. Higher air pressure below the kite and lower air pressure above it lead to an upward force that keeps the kite aloft.


What is upward force of liquid or gas?

The upward force exerted by a liquid or gas on an object immersed in it is called buoyant force. This force is a result of the pressure difference between the top and bottom of the object, and it opposes the weight of the object, causing it to float or rise.


What is Flowing air responding to the difference between higher and lower pressure is responding to what?

Flowing air responds to the difference in pressure between higher and lower pressure areas by moving from high pressure to low pressure to equalize the pressure. This movement of air creates wind, which is the result of the pressure difference seeking equilibrium.


What is the driving force in filtration?

The driving force in filtration is the pressure difference between the two sides of the filter. This pressure gradient pushes the liquid or gas through the filter, separating the particles based on size and allowing the filtrate to pass through while retaining the larger particles.

What is the formula for vaccum force?

The formula for vacuum force can be calculated as: Vacuum force = Pressure difference x Area Where the pressure difference is the difference in pressure between the vacuum and the surrounding atmosphere, and the area is the surface area over which the force is acting.


What is the upward force due to a pressure difference between the top and bottom of a wing?

The upward force due to a pressure difference is called lift. It is generated when the air pressure below the wing is higher than the pressure above the wing, creating a pressure difference that causes the wing to be pushed upward.

What is the driving force of different unit operations?

The driving force of different unit operations can vary depending on the specific process involved. For example, in distillation, the driving force is the difference in vapor pressure between the components being separated. In filtration, the driving force is the pressure difference across the filter medium. In heat exchangers, the driving force is the temperature difference between the two fluids exchanging heat.

What is the origin of upthrust in fluid?

Upthrust in fluid, also known as buoyant force, is caused by the pressure difference between the top and bottom of an object submerged in a fluid. This pressure difference creates a net force pushing the object upwards. It is a result of Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.


Why does the buoyancy force on an object act upward?

The buoyancy force is the upward force exerted on an object immersed in a fluid due to the pressure difference between the top and bottom of the object. This pressure difference results in a net upward force that is greater than the downward force of gravity, causing the object to float.


This force describes how water exerts an upward force on submerged objects?

This is called a "bouyant" force. It is due to the difference in water pressure between the top of the object and the bottom of the object. Water pressure increases with depth.


What is a pressure gradient and how is it related to air movement?

Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
