Pressure in Fluids:
Hydrostatic Pressure: The pressure exerted by a fluid at rest due to the weight of the fluid above a point. It increases with depth in a fluid.
Applications of Pressure:
Atmospheric Pressure: The pressure exerted by the Earth's atmosphere. Standard atmospheric pressure at sea level is approximately 101.3 kPa.
Blood Pressure: The pressure of circulating blood against the walls of blood vessels. It is typically measured in millimeters of mercury (mmHg) or kilopascals (kPa).
