pressure gradientpressure gradient
Pressure gradient is how much the atmospheric pressure lowers in an area at a specific time.
An example of a pressure gradient is gale force winds turning into a light breeze in a specific city after an hour.
the rate of decrease in barometric pressure in a given region at a particular time
- The resultant force is therefore in the direction of the steepest pressure-gradient, and this is normal to the surface of equal pressure; for equilibrium to exist in a fluid the lines of force must therefore be capable of being cut orthogonally by a system of surfaces, which will be surfaces of equal pressure.
- As a rule these equations are established immediately by determining the component acceleration of the fluid particle which is passing through (x, y, z) at the instant t of time considered, and saying that the reversed acceleration or kinetic reaction, combined with the impressed force per unit of mass and pressure-gradient, will according to d'Alembert's principle form a system in equilibrium.
