Difference in pressure is the difference in force per unit area between two points in a fluid or gas. It is commonly measured in units of pressure, such as Pascal or pounds per square inch (psi).
Difference in pressure can be calculated by subtracting the pressure at one point from the pressure at another point. This gives the net force acting on a unit area at that point.
A difference in pressure can be caused by a variety of factors, including changes in temperature, velocity, and elevation. It can also be caused by the presence of obstacles or barriers in the flow of a fluid or gas.
Difference in pressure plays a crucial role in fluid dynamics, as it is responsible for the movement of fluids and gases. It is the driving force behind phenomena such as wind, ocean currents, and the flow of blood in the human body.
Difference in pressure is used in various practical applications, such as in weather forecasting, aviation, and hydraulics. It is also used in the design and operation of devices such as pumps, turbines, and engines.
