Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it.
Imagine you are at the bottom of a swimming pool. The deeper you go, the more water is above you, and you can feel an increasing pressure on your body. This pressure is similar to hydrostatic pressure, where the weight of the fluid column above determines the force exerted on an object submerged in it.
Pascal (Pa): Pascal is the SI unit for measuring pressure. It is defined as one newton per square meter.
Manometer: A manometer is a device used to measure and indicate the pressure of fluids. It consists of a U-shaped tube filled with liquid that responds to changes in fluid pressure.
Gauge Pressure: Gauge pressure refers to the difference between absolute pressure and atmospheric pressure. It measures how much higher or lower a fluid's pressure is compared to atmospheric conditions.
