pressure gradient
When there is a great difference in air pressure between two areas, winds are strong. The air moves from high pressure to low pressure, causing faster winds to equalize the pressure difference.
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
Wind blows from an area of high pressure to an area of low pressure. This movement is driven by the difference in air pressure between the two areas. The greater the pressure difference, the stronger the wind will be.
Heating a can and then submerging it in water can create a pressure difference between the inside and outside of the can. When the can is rapidly cooled in water, the pressure difference causes the can to collapse due to the external pressure being greater than the internal pressure.
velocity is a distance travelled per sec

A fast flowing river is faster
what is the difference between thrust and pressure?
Air moves from high to low pressure due to the natural tendency of air molecules to spread out and equalize pressure. This movement is driven by the pressure difference between two areas, with air flowing from areas of higher pressure to areas of lower pressure in order to balance out the pressure gradient.
Differential pressure is the difference in pressure between two points in a fluid system, while static pressure is the pressure at a single point in the system.
The pressure difference formula is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points. To calculate the pressure difference between two points, you can use this formula by plugging in the values for the density of the fluid, acceleration due to gravity, and the height difference between the two points.
A pitot tube uses Bernoulli's equation to measure fluid flow velocity by comparing the pressure difference between the stagnation point and the dynamic pressure of the fluid. This difference in pressure is used to calculate the velocity of the fluid flowing past the pitot tube.
Pulse pressure is the difference between the systolic and diastolic blood pressure readings.
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
The differential pressure equation used to calculate the pressure difference between two points in a fluid system is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points.
