The specific weight of a fluid is the product of the fluid's density and the acceleration
due to gravity.
Stronger surface tension leads to higher capillary rise.
Absolute pressures are frequently negative.
If the pressure of fluid drops below the vapor pressure of that fluid at that

Density can be measured in lb;/ft° in the English system of units.
For a hydrostatic incompressible fluid, pressure is independent of depth.
A fluid with a high bulk modulus of elasticity is more difficult to compress than one
with a low bulk modulus of elasticity.
Viscosity is caused, in part, by the surface tension within a fluid.
A fluid can resist an applied shear stress by deforming.
