Unit weight is defined as the weight per unit volume

Piezometer is the simplest type of manometer

The resultant pressure on any plane in a fluid at rest is normal/perpendicular to that plane

Vacuum indicates the amount of negative gage pressures

Water is the least viscous of all fluids

Liquid is capable of flowing, have particles that can easily move, and can readily conform to the shape of solid with which they come in contact with

Specific gravity is the ratio of the density of the fluid to the density of water

Gage pressure is measured relative to absolute zero pressure

Viscosity determines the amount of its resistance to a shearing stress

Pascal’s Law indicates that at any point in a fluid at rest, the pressure is the same in all directions
